Small things I really like about your site: 1) "share the love" icons; 2) ability to log in using my twitter account (you should make it more visible, missed it the first time); 3) the way updates are formulated: <user> <action> <status> (particulary "user replied to another_user" is so much better than Twitter's); 4) rocks!/sucks! reviews

Good luck to you and many satisfied users!
