The registration form is terrible: each time it doesn't like some input all the fields are reset and you have to start from scratch. Then the website URL validation is broken: for instance, I can't use a domain with a hyphen for it, but I can in the e-mail field. Also, the twitter field could be optional, and in any case tolerate getting the handle with the @ symbol prefixed. Anyway, the really bad part is the first point because it promotes the others from annoyances into pain. The site looks good, though. It might end up working very well with some refinements as others noted.
