So Scoble’s looking for a wiki, seems to have gotten a few popular suggestions. Since he wants it hosted I can’t really offer anything – I don’t have the server space or sysadmin knowledge to handle something of Scoble’s popularity. Despite that, can I recommend that you make the quality of the editor your most important criteria? It will make a huge difference to the adoption rate of the wiki. I’ve discussed this before: Wiki Syntax Considered Harmful and Making Wikis Work.

Of course if for some reason you wind up hosting your own wiki or otherwise have access to the back end, I’m sure I could arrange for Ephox to donate a license to a really good WYSIWYG editor. I can donate my spare time to integrate it into whatever wiki you were looking at. In any case, I’d love to hear what you wound up going with.
