I added AdSense as a small way of getting to know a hugely significant part of the net a little better through direct experience. My revenue expectations were met over the years — trivial, due to trivial traffic and relatively innocuous placement. Viewing my blog with a browser sans adblock and with flash for the first time in perhaps years just now prompted the removal and this post, which I had planned to do in the fullness of time — the innocuous placement was still ugly, and with flash enabled all of the ads are graphical and many animated. Clearly I have learned all I am capable of learning via this experiment, which I am glad I did. If I ever have something characterized as third party ads here again, it’ll be via some very different mechanism.
Relatedly, I’ve meant to recommend Don Marti’s blog for a long time, when I got around to saying and doing more about net advertising, but don’t wait for me.
