Wikis have the capability to become, with a strong enough userbase, the best resources on whatever they pertain to (case-in-point, Wikipedia). I'm a little reserved about this one, though, because of its interface. In my opinion, a Wiki should be abhorrently simple, clear, and concise. This seems to be another CMS with another techno-style theme added to it.
Of course, with the content, I could be wrong, we'll have to wait and see. I would have a much better impression of it if it were along the lines of the MediaWiki software.
