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.
If the government told me that my “score” dictating my ability to participate in society would be greatly affected based on what I thought of the government, I’d support the heck out of that government too.
