Wikipedia advertising redux

Monday, January 8th, 2007

Many good comments regarding supporting advertising on Wikipedia (or not) here and also on Slashdot and other blogs. I may further characterize and respond to these in aggregate (see the update to my first post for some of this). For now I want to call out or respond to a few particularly worthy comments and criticisms.

Evan Prodromou’s comment:

One thing I wanted to respond to was that a couple of people seemed to think it incorrect on my part to refer to Wikipedia’s Web traffic as a “resource”. I’m not sure what else to call a potential source of tens, maybe hundreds of millions of dollars annually in income. But if people know a better word for it, please substitute that in.

Let me also point out that wikipedia.org’s current huge Web traffic is not a long-term sure thing. As Open Content, the encyclopedia can be copied onto any other Web site on the Internet, and sites like answers.com show that this can be lucrative. Anyone familiar with the Open Directory (http://dmoz.org/) knows that it’s copied to Google Categories, Yahoo Directory, and dozens of other high-profile sites. In 5 years, will there be thousands of mirrors of Wikipedia on the Web? Will wikipedia.org become more like editors.dmoz.org — an editorial interface for a data set served from many other servers?

If that’s the case, will we look back on the high-traffic days of 2005-2008 as the time when we wasted somewhere around half a billion dollars in potential revenue? Will the WMF really be glad at that point that it did so?

I hadn’t thought of this scenario and don’t consider it likely, but do think it is an important consideration. I think the canonical was seriously disadvantaged in two ways Wikipedia is not — a fairly closed editorial process (e.g., I’ve applied a few times over the years and don’t recall getting any feedback, not even rejection) and probably a horrible editor interface (e.g., I was accepted as an editor at Chef Moz, a sister site of dmoz.org — and ran away screaming).

How could Wikimedia sites lose traffic to copies? Presumably much of Wikipedia traffic comes from Google. If Google published a branded copy (with ads of course) and promoted it in (or above) search results, Wikipedia would presumably lose lots of traffic (and many people would call Google evil for it, at least for awhile). I’m sure there are more creative scenarios in which Wikimedia sites lose traffic.

Peter McCluskey:

Mike Linksvayer has a fairly good argument that raising X dollars by running ads on Wikipedia won’t create more conflict of interest than raising X dollars some other way.

Almost. The second X is Y and an order of magnitude or so smaller than X. McCluskey:

But the amount of money an organization handles has important effects on its behavior that are somewhat independent of the source of the money, and the purpose of ads seems to be to drastically increase the money that they raise.

I can’t provide a single example that provides compelling evidence in isolation, but I think that looking at a broad range of organizations with $100 million revenues versus a broad range of organizations that are run by volunteers who only raise enough money to pay for hardware costs, I see signs of big differences in the attitudes of the people in charge.

Wealthy organizations tend to attract people who want (or corrupt people into wanting) job security or revenue maximization, whereas low-budget volunteer organizations tend to be run by people motivated by reputation. If reputational motivations have worked rather well for an organization (as I suspect the have for Wikipedia), we should be cautious about replacing those with financial incentives.

It’s possible that the Wikimedia Foundation could spend hundreds of millions of dollars wisely on charity, but the track record of large foundations does not suggest that should be the default expectation.

Yes, this could be a major problem. As I said last year, “[advertising] could fund a staggering Wikimedia Foundation bureaucracy, or it could fund additional free knowledge projects.” The possibility that new funds will not be used effectively lowers the expected benefit of running ads. Two items give me some confidence that the Wikimedia Foundation would be less susceptible to waste than the average foundation:

  • Wikimedia Foundation’s history of transparency sets the tone for what would become a much larger organization
  • An incomparable set of watchdogs (Wikipedians)

Regarding subversion of current volunteer motivations and ethics (which is really the point of McCluskey’s post), I would not advocate financial incentives for functions currently carried out by volunteers, certainly not any content-related function. Of course given large amounts of money there would be pressure to convert an ever larger group of volunteers into employees, regardless of what advocates of advertising on Wikipedia might have wanted. The possibility that this would occur and go badly should also weigh against advertising.

Addressing this possibility, I concur with Per Abrahamsen’s recommendation segregating Wikimedia projects and foundation funding of compatible projects:

Wikipedia is clearly able to earn its own money, begging for donations on the front (and every other) page is an insult to both visitors, and to the many worthy cases that are not in that lucky position.

So I support advertising on Wikipedia.

The adds should be non-intrusive, textual, clearly separated from content, and selected algorithmically, similar to the adds known from Google.

However, if the money are really that big (more than the current need), additional precautions would have to be taken. The most important would be to split the foundation into two, with watertight boundaries between. One that ran the current Wikimedia projects, and another solely responsible for distribution the ad-money between causes that promote the goals of the foundation, but had no say in the running of any of the projects. Money do corrupt, hence the separation.

Slashdot commenter FooAtWFU (and others) suggested that the real problem with advertising is that large numbers of contributors would leave in protest, seriously damaging Wikipedia. I doubt it. A very vocal minority would raise hell and some of them would leave, at least temporarily. I suspect most contributors would not even notice the presence of ads. I conjecture that Wikipedia contributors, however superior some may feel, are not that different from MySpace “contributors” (who seem not to be deterred by gratutous advertising). In a relatively short time (a year is my wild guess) a majority of contributors would have become contributors after advertising had begun. Such is the nature of a rapidly growing site.

A 2002 fork of () could be interpreted as evidence in either direction. The fork apparently occurred in part due to “our rejection of censorship, of an editorial line, and of including advertising.” Whatever the merits of these claims, article counts show the fork growing more quickly for about a year and a half. From 2004 on Spanish Wikipedia grew much more quickly and currently is over five times the size of Enciclopedia Libre. So the loss of those ideologically motivated against advertising and perhaps with other complaints could be seen as a terrible blow to Spanish Wikipedia (a year or more delayed progress) or no big deal, considering current relative sizes. Is there any reason to think the proportion of Spanish Wikipedians disgusted by advertising is significantly different than that of any other language?

Of course it is possible if Wikipedia had taken ads in 2002, many more may have left, and perhaps the fork would now be five times the size of the parent instead of vice versa. This would not necessarily be a horrible thing. After all, the two sites (and any potential Wikipedia fork) use the same license, so work done on one is not entirely lost to the other.

This does suggest an experiment however — run ads on Spanish Wikipedia and see how many contributors move to Enciclopedia Libre. The existence of the latter would make it both easier for ad objectors to move and easier to determine who had moved, indicating a probable maximum negative impact on contributions to other Wikipedias, should they run ads, as no other language has an alternative as viable as Enciclopedia Libre — at least not viable for those who hate ads! The largest encyclopedic wikis outside Wikimedia run Google AdSense, e.g., (Russian) and (Swedish).

BlackNet is a wiki?

Sunday, January 7th, 2007

Wikileaks, currently vapor, may be a joke. If Wikileaks is not a joke and if it successfully exposes a large number of secrets, I’d find it hilarious to see this happening on a public website and without financial incentives. P2P, digital cash, information markets, and crypto anarchy? Nope, just a wiki and a communinty.

Wikileaks FAQ:

WikiLeaks will be the outlet for every government official, every bureaucrat, every corporate worker, who becomes privy to embarrassing information which the institution wants to hide but the public needs to know. What conscience cannot contain, and institutional secrecy unjustly conceals, WikiLeaks can broadcast to the world.

Untraceable Digital Cash, Information Markets, and BlackNet (1997, but these ideas spread widely in the early 1990s):

One of the most interesting applications is that of “information markets,” where information of various kinds is bought and sold. Anonymity offers major protections for both buyers and sellers, in terms of sales which may be illegal or regulated. Some examples: corporate secrets, military secrets, credit data, medical data, banned religious or other material, pornography, etc.

Why is more information not leaked on the net already? The technology exists to do so anonymously and has for a long time. Why is there not (or to what extent is there) a market for secrets? Again, the technology exists.

Perhaps lack of the relevant institutions in each case. One could email secrets or post to a blog anonymously, but what then? Will anyone notice? One could want to sell secrets, but how to find a buyer?

If Wikileaks succeeds it will be because it will provide, or rather its community will be, the relevant institution. Again from the Wikileaks FAQ:

WikiLeaks opens leaked documents up to a much more exacting scrutiny than any media organization or intelligence agency could provide: the scrutiny of a worldwide community of informed wiki editors.

Instead of a couple of academic specialists, WikiLeaks will provide a forum for the entire global community to examine any document relentlessly for credibility, plausibility, veracity and falsifiability. They will be able to interpret documents and explain their relevance to the public. If a document is leaked from the Chinese government, the entire Chinese dissident community can freely scrutinize and discuss it; if a document is leaked from Somalia, the entire Somali refugee community can analyze it and put it in context.

I have not read the Wikileaks email archived at cryptome.

I support advertising on Wikipedia

Tuesday, January 2nd, 2007

Wikimedia Foundation is over halfway through a . I hope that when you give you leave the following public comment:

I support advertising on Wikipedia.

Evan Prodromou summarizes a completely unwarranted controversy regarding a matching fund (bottom of page):

All fine so far, right? But a small logo in the donations notice — seen by non-logged-in users on every page of every WMF site — was considered by many Wikipedians and other WMF editors as dangerously close to the line on advertising — or over it. There have been several prominent users who have left the project because of it.

I’m not sympathetic with these folks; in fact, I’m in solid opposition. I think that Wikipedia’s huge amount of Web traffic is a resource that the Foundation is squandering. Traffic like Wikipedia’s is worth tens of millions if not hundreds of millions of dollars in ad revenue per year. That’s money that could go to disseminate free (libre and gratis) paperback pocket encyclopedias to millions of schools and millions of children, in their own language, around the world.

It’s irresponsible to abuse that opportunity.

I strongly agree and will repeat exactly what I said during last year’s Wikimedia fund drive:

Wikipedia chief considers taking ads (via Boing Boing) says that at current traffic levels, Wikipedia could generate hundreds of millions of dollars a year by running ads. There are strong objections to running ads from the community, but that is a staggering number for a tiny nonprofit, an annual amount that would be surpassed only by the wealthiest foundations. It could fund a staggering Wikimedia Foundation bureaucracy, or it could fund additional free knowledge projects. Wikipedia founder Jimmy Wales has asked what will be free. Would an annual hundred million dollar budget increase the odds of those predictions? One way to find out before actually trying.

In somewhat related news, Mozilla just reported 2005 financial information, showing 800% revenue growth:

In 2005 the Mozilla Foundation and Mozilla Corporation combined had revenue from all sources of $52.9M. $29.8M of this was associated with the Foundation (both before and after the creation of the Corporation). The bulk of this revenue was related to our search engine relationships, with the remainder coming from a combination of contributions, sales from the Mozilla store, interest income, and other sources. These figures compare with 2003 and 2004 revenues of $2.4M and $5.8M respectively, and reflect the tremendous growth in the popularity of Firefox after its launch in November 2004.

The combined expenses of the Mozilla Foundation and Corporation were approximately $8.2M in 2005, of which approximately $3M was associated with the Foundation. By far the biggest portion of these expenses went to support the large and growing group of people dedicated to creating and promoting Firefox, Thunderbird, and other Mozilla open source products and technologies. The rate of expenses increased over the year as new employees came on board. The unspent revenue provides a reserve fund that allows the Mozilla Foundation flexibility and long term stability.

An advertising-fueled Wikimedia Foundation could fund dozens of much needed Mozilla Firefox sized projects. And many Creative Commons (which just successfully completed its much more modest annual funding campaign) initiatives. :)

Update: Welcome Slashdot readers. The major objection to ads on Wikipedia takes two forms:

  • Advertising is profane.
  • Advertising would compromose Wikipedia’s neutrality.

A common response to the first is that those who don’t like ads can run an ad blocker. Easier still, those who don’t like ads can log in — there’s little reason to display ads to logged in users, who probably generate a tiny fraction of pageviews. But I don’t think either of these responses will satisfy this form of the objection, as it is basically emotional. Some people object to the knowledge that ads exist, even if not experienced personally. I suppose these people don’t use search engines. It’s a wonder they can stand to use the net at all. I discount them completely.

The second is completely unrealistic. How would third party text ads, e.g., via AdSense, compromise neutrality? There’s simply no vector for an advertiser to demand changes and zero reason for Wikipedians to comply. Wikipedia is not a small town newspaper beholden to the local department store, not even close. It isn’t even Slashdot, which as far as I can tell has not been compromised by years of running ads. To people with this objection: show me a community site that has gone astray due to advertiser influence.

Sponsors, “being managed by Wikipedia staff (like in newspaper ads, i.e. no uncontrolled 3rd party feeds)”, as suggested by Kuba Ober, are far more dangerous than third party ads, because then there is a vector between advertiser and someone with power at Wikipedia.

There may be an opportunity for Wikipedia to completely rethink and remake advertising, or merely compete in some fashion with what some are calling Google’s near monopoly, but now it would make tremendous sense to use AdSense or Yahoo! or both — and I suspect Wikipedia could manage to keep a greater share of revenue than a normal web publisher. Rick Yorgason mocked up what AdSense would look like in the place of the current fundraiser’s donation banner.

Slashdot commenter jklooserman summarizes objections from Wikiproject no ads:

  1. Wikipedia’s philosophy is non-commercial
  2. Ads put at risk Wikipedia’s principle of Neutral Point of View (NPOV)
  3. The information that constitutes Wikipedia is wealth for the community

I don’t see “non-commercial” in any form on the Wikimedia Foundation home page. I do see this, in large text:

Imagine a world in which every single human being can freely share in the sum of all knowledge. That’s our commitment.

The next line, all bold, asks for help in the form of donations.

Much more money, hundreds of millions, would speed the arrival of that world and fulfillment of that commitment.

As above, there is no realistic scenario for ads undermining neutrality on Wikipedia.

The third objection strikes me as a non-sequitur. In any case, the point of obtaining more resources would be to increase the wealth of the community — of all human beings.

jklooserman also pointed out that there’s a category of Wikipedians who think that the Wikimedia Foundation should use advertising. Add it to your user page if you agree.

You against abominable people

Saturday, December 16th, 2006

On Time magazine’s person of the year, Chris F. Masse writes:

TIME is right on target, but their thematic articles are banal and not engaging. Complete crap.

Agreed on both points.

I am happy to see that in praising dispersed contributors to the net Time took the opportunity to bash “great men” (emphasis added):

The “Great Man” theory of history is usually attributed to the Scottish philosopher Thomas Carlyle, who wrote that “the history of the world is but the biography of great men.” He believed that it is the few, the powerful and the famous who shape our collective destiny as a species. That theory took a serious beating this year.

To be sure, there are individuals we could blame for the many painful and disturbing things that happened in 2006.

Yes, because it is only possible to be “great” through doing great harm. Time:

But look at 2006 through a different lens and you’ll see another story, one that isn’t about conflict or great men. It’s a story about community and collaboration on a scale never seen before. It’s about the cosmic compendium of knowledge Wikipedia and the million-channel people’s network YouTube and the online metropolis MySpace. It’s about the many wresting power from the few and helping one another for nothing and how that will not only change the world, but also change the way the world changes.

Yes, it is the anti-authoritarian age. Time:

But 2006 gave us some ideas. This is an opportunity to build a new kind of international understanding, not politician to politician, great man to great man, but citizen to citizen, person to person.

Even more of a stretch, I’ll take opportunity to link in another of my pet peeves.

The short person of the year article also references directly or indirectly Wikipedia, blogs, open source, peer production, and free culture.

I occasionally wonder what it would feel like to read a mass media article and more or less think “right on!” Now that I have encountered such an article, should I enjoy it, reconsider what makes me agree, considering the source, or reconsider my assumption that Time and similar are emotionalized diarrhea magazines rather than news magazines, just like TV?

Most important software project

Sunday, December 10th, 2006

I don’t have a whole lot more to say about Semantic MediaWiki than I said over a year ago. The summary is to turn the universal encyclopedia into the universal database while simultaneously improving the quality of the encyclopedia.

Flip through Denny Vrandecic’s recent presentations on Semantic MediaWiki (a smaller pdf version not directly linked in that post). There’s some technical content, but flip past that and you should still get the idea and be very excited.

I predict that Semantic MediaWiki also will be the killer application for the Semantic Web that so many have been skeptical of.

Yaron Koren also says that Semantic MediaWiki is “the technology that will revolutionize the web” and has built DiscourseDB using the software. DiscourseDB catalogs political opinion pieces. Koren’s post on aggregating analysis using DiscouseDB. Unsurprisingly this analysis shows the political experts making bad calls.

Koren also has created Betocracy, another play money prediction market where users create claims. It looks like Betocracy is going for a blog-like interface, but I can’t say more as registration obtains a database error.

One prediction market and Semantic MediaWiki connection is that making data more accessible makes prediction markets more feasible. Obtaining data necessary to create and judge prediction market contracts is expensive.

On that note Swivel also looks interesting. Some have called it data porn. Speaking of porn, see Strange Maps.

Embrace the public domain

Sunday, November 26th, 2006

Peter Saint-André published his promised essay Who’s Afraid of the Public Domain?. It’s fairly short and covers a fair amount of ground. I highly recommend it. Two of my favorite paragraphs:

Yet the public domain is nothing to fear. The works of Homer, Sophocles, Confucius, Plato, Aristotle, Dante, Shakespeare, Galileo, Newton, Bach, Beethoven, and other creative giants are all in the public domain. Their works are revered, not reviled. Sure, the fact that the Fifth Symphony is in the public domain enabled Chuck Berry to write “Roll Over Beethoven”; but far from defiling Beethoven’s good name, Berry’s song indicates the level of respect that we still have for Beethoven’s works. I bet you’d love it for your works to be similarly known and respected two hundred years from now (what creative individual wouldn’t?).

Because of that corporate influence over the copyright laws (at least in America), you face a choice: accept that your works will never pass into the public domain, or willingly place them there. You can place your works into the public domain immediately (as I have done) or specify in your will that your works shall pass into the public domain upon your death. I find it simpler to place my works in the public domain as soon as I publish them, but only you can decide the best course of action for your own works.

I would add that if you don’t make an effort to free your works, they will disappear, and your creative legacy with them.

One item of fear, uncertainty and doubt spread about the public domain (that would have been out of scope for Saint-André’s essay to address) is that it may not be possible legally to affirmatively place a work into the public domain (see Wikipedia:Granting work into the public domain for some discussion), especially outside the U.S. jurisdiction.

I believe wikipedians attempt to work around this with statements like the one currently in Template:Userpd (emphasis added):

I, the author, hereby agree to waive all claim of copyright (economic and moral) in all content contributed by me, the user, and immediately place any and all contributions by me into the public domain; I grant anyone the right to use my work for any purpose, without any conditions, to be changed or destroyed in any manner whatsoever without any attribution or notice to the creator.

Or one of many specialized “public domain or release all rights legally possible” templates like this one:

This image really is in the Public domain as its author has released it into the public domain. If this is not possible, the author grants anyone the right to use this work for any purpose, without any conditions, unless such conditions are required by law.

I have no idea what a court would make of these, but presumably someone has or will inform the Wikipedia community if they are bogus.

If you aren’t ready to fully embrace the public domain, Creative Commons offers several gradations of partial measures (as well as a form to help you dedicate work to the public domain).

Check out all of Saint-André’s posts about the public domain and digg his essay.

Defeatist dreaming

Sunday, October 22nd, 2006

Jimmy Wales of Wikipedia says to dream a little:

Imagine there existed a budget of $100 million to purchase copyrights to be made available under a free license. What would you like to see purchased and released under a free license?

I was recently asked this question by someone who is potentially in a position to make this happen, and he wanted to know what we need, what we dream of, that we can’t accomplish on our own, or that we would expect to take a long time to accomplish on our own.

One shouldn’t look a gift horse in the mouth and this could do a great deal of good, particularly if the conditions “can’t accomplish on our own…” are stringently adhered to.

However, this is a blog and I’m going to complain.

Don’t fork over money to the copyright industry! This is defeatist and exhibits static world thinking.

$100 million could fund a huge amount of new free content, free software, free infrastructure and supporting institutions, begetting more of the same.

But if I were a donor with $100 million to give I’d try really hard to quantify my goals and predict the most impactful spending toward those goals. I’ll just repeat a paragraph from last December 30, Outsourcing charity … to Wikipedia:

Wikipedia chief considers taking ads (via Boing Boing) says that at current traffic levels, Wikipedia could generate hundreds of millions of dollars a year by running ads. There are strong objections to running ads from the community, but that is a staggering number for a tiny nonprofit, an annual amount that would be surpassed only by the wealthiest foundations. It could fund a staggering Wikimedia Foundation bureaucracy, or it could fund additional free knowledge projects. Wikipedia founder Jimmy Wales has asked what will be free. Would an annual hundred million dollar budget increase the odds of those predictions? One way to find out before actually trying.

Friends don’t let friends click spam

Thursday, September 7th, 2006

Doc Searls unfortunately decided the other day that offering his blog under a relatively restrictive Creative Commons NonCommercial license instead of placing its contents in the public domain is chemo for splogs (spam blogs). I doubt that, strongly. Spam bloggers don’t care about copyright. They’ll take “all rights reserved” material, that which only limits commercial use, and stuff in the public domain equally. Often they combine tiny snippets from many sources, probably triggering copyright for none of them.

A couple examples found while looking at people who had mentioned Searls’ post: all rights reserved material splogged, commenter here says “My blog has been licensed with the CC BY-NC-SA 2.5 for a while now, and sploggers repost my content all the time.” A couple anecdotes prove nothing, but I’d be surprised to find that sploggers are, for example, using CC-enabled search to find content they can legally re-splog. I hope someone tries to figure out what characteristics make blog content more likely to be used in splogs and whether licensing is one of them. I’d get some satisfaction from either answer.

Though Searls’ license change was motived by a desire “to come up with new forms of treatment. Ones that don’t just come from Google and Yahoo. Ones that come from us” I do think blog spam is primarily the search engines’ problem to solve. Search results that don’t contain splogs are more valuable to searchers than spam-ridden results. Sites that cannot be found through search effectively don’t exist. That’s almost all there is to it.

Google in particular may have mixed incentives (they want people to click on their syndicated ads wherever the ads appear), but others don’t (Technorati, Microsoft, Ask, etc. — Yahoo! wishes it had Google’s mixed incentives). At least once where spam content seriously impacted the quality of search results Google seems to have solved the problem — at some point in the last year or so I stopped seeing Wikipedia content reposted with ads (an entirely legal practice) in Google search results.

What can people outside the search engines do to fight blog and other spam? Don’t click on it. It seems crazy, but clickfraud aside, real live idiots clicking on and even buying stuff via spam is what keeps spammers in business. Your uncle is probably buying pills from a spammer right now. Educate him.

On a broader scale, why isn’t the , or the blogger equivalent, running an educational campaign teaching people to avoid spam and malware? Some public figure should throw in “dag gammit, don’t click on spam” along with “don’t do drugs.” Ministers too.

Finally, if spam is so easy for (aware) humans to detect (I certainly have a second sense about it), why isn’t human-augmented computation being leveraged? Opportunities abound…

Sex on Wikipedia

Monday, August 28th, 2006

I was surprised for a moment to see that sex and porn related articles are among the most popular on Wikipedia. From a list of the 100 most viewed articles on Wikipedia this month:

Views per day Percent Rank and Title
18500 ± 134% 0.0724% 7.
18000 ± 136% 0.0705% 8.
17000 ± 140% 0.0666% 10.
15500 ± 147% 0.0607% 13.
14500 ± 152% 0.0568% 15.
14500 ± 152% 0.0568% 16.
13000 ± 160% 0.0509% 19.
12000 ± 167% 0.0470% 24.
11500 ± 171% 0.0450% 34.
10500 ± 178% 0.0411% 38.
9000 ± 193% 0.0352% 56.
9000 ± 193% 0.0352% 63.
8500 ± 198% 0.0333% 70.
8000 ± 204% 0.0313% 78.

Of course I shouldn’t have been surprised. Wikipedia content should more or less mirror that of the Internet, media in general, and human thoughts and conversation: sex is big, but not dominant.

I haven’t looked at a normal encyclopedia in ages, but I suspect sex would be seriously underrepresented.

Now I want to know whether Arabic Wikipedia has articles on sex (there is currently no interlanguage link to the Arabic Wikipedia from the English Sex article) and if so are they relatively even more popular than their English counterparts. If not I smell opportunity for Arabic-literate Wikipedians.

Wordcamp and wiki mania

Monday, August 7th, 2006

In lieu of attending maybe the hottest conference ever I did a bit of wiki twiddling this weekend. I submitted a tiny patch (well that was almost two weeks ago — time flies), upgraded a private MediaWiki installation from 1.2.4 to 1.6.8 and a public installation from 1.5.6 to 1.6.8 and worked on a small private extension, adding to some documentation before running into a problem.

1.2.4->1.6.8 was tedious (basically four successive major version upgrades) but trouble-free, as that installation has almost no customization. The 1.5.6->1.6.8 upgrade, although only a single upgrade, took a little fiddling make a custom skin and permissions account for small changes in MediaWiki code (example). I’m not complaining — clean upgrades are hard and the MediaWiki developers have done a great job of making them relatively painless.

Saturday I attended part of , a one day unconference for WordPress users. Up until the day before the tentative schedule looked pretty interesting but it seems lots of lusers signed up so the final schedule didn’t have much meat for developers. Matt Mullenweg’s “State of the Word” and Q&A hit on clean upgrade of highly customized sites from several angles. Some ideas include better and better documented plugin and skin APIs with more metadata and less coupling (e.g., widgets should help many common cases that previously required throwing junk in templates).

Beyond the purely practical, ease of customization and upgrade is important for openness.

Now listening to the Wikimania Wikipedia and the Semantic Web panel…
