Something like Uberfact should absolutely be built, though I’m far from certain it would hit a sweet spot. It may be too decentralized or too centralized or both. All points from enhancing Wikipedia to the Semantic Web (with Uberfact somewhere between) are complementary and well worth pursuing, particularly if that pursuit displaces malinvestment in politics.
