Is anybody working on an alternative to Wikipedia?

Larry Sanger (wikipedia creator) is working on the encyclophere: https://www.youtube.com/watch?v=8Esw3gXK82Y Description from that video: Shorter video: https://www.youtube.com/watch?v=8PrWG... The Encyclosphere will be a decentralized, leaderless, centerless network of encyclopedic content, which does for encyclopedias what the Blogosphere did for blogs. But to make such a network, we need encyclopedia format standards. Wikipedia ex-founder Larry Sanger is starting the Knowledge Standards Foundation to convene a discussion and coding efforts to creating such standards.

I know of h2g2 - https://www.h2g2.com/ .

Wikipedia ('natch) has a list at https://en.wikipedia.org/wiki/List_of_online_encyclopedias .

Considering the quality of Wikipedia and the effort that has gone into it, why would anyone attempt to work on an alternative?
