@bcambel: in the Clojure spirit of being hosted, I sincerely think the community is would benefit more from leveraging mature platforms like Google Groups, StackOverflow, Gitter, Github etc.

I do think there's room for more community sites though, but they should be innovative and be suited to the specifiics of the language IMHO

as far as I know, Clojure is well represented on all of the sites you mentioned
