This feels like a hasty "solution" to an invented "problem". Sure, Wikipedia isn't squeaky clean, but it's pretty damn good for something that people have been freely adding knowledge to for decades. The cherry-picked examples of what makes Wikipedia " bad" are really not outrageous enough to create something even more niche than Wikia, Fandom, or the late Encyclopedia Dramatica. I appreciate the thought, but federation is not a silver bullet for everything. Don't glorify federation the way cryptobros glorify the block chain as the answer to all the problems of the world.
