Tim-
Jimbo said he wanted it. As far as I'm concerned, developers are still answerable to him not the other way around. If you want to hold a site wide vote, go for your life. If there's enough support, we'll delete the wiki.
No, that is incorrect. Jimbo said: "For example, it would be bad to have a Klingon Wikipedia, I think." http://mail.wikipedia.org/pipermail/wikipedia-l/2004-May/015324.html
Given that your action was based on a false premise, please disable the wiki now.

Erik
