Is there any good resource for wiki management?

Well, there are quite a few forums talking about forum management (like Admin Talk and the like) and a few talking about blog management/writing, but is there any such resource for wiki management?

After all, wikis are a type of community platform that needs specialist knowledge for an admin to use and promote well, but I can't seem to find any forums or guides talking about how best to run one and make it popular. What people actually want in a wiki, why some don't succeed and others do, etc.

So yeah, is there an Admin Talk like resource for wiki owners and users?
