I'm going to just say that I'm exteremely sceptical on how this will turn out, just because there has been quite a few Wikipedia forks that have not exactly worked out despite the best interests and the stated objectives they had.

Now - Wikipedia isn't exactly an entity that doesn't have glaring problems of its own, of course - but I'm just saying that the wiki model has been tried out a lot of times and screwed up many times in various weird ways.

There's exactly two ways I can see Wikipedia forks to evolve: Crappily managed fork that is handled by an ideological dumbass that attracts a crowd that makes everything much worse (e.g. Conservapedia, Citizendium), or a fork that gets overrun by junk and forgotten by history, because, well, clearly it's much more beneficial to contribute to Wikipedia anyway.

I was about to respond with a copy of the standard Usenet spam response form with the "sorry dude I don't think this is going to work" ticked, but Google is shit and I can't find a copy of that nonsense anymore, so there.
