New 2.0 Forum Software (competition?)
http://www.esotalk.com What do you guys think of this new forum software offering? It instantly reminded me of Vanilla. I think it has some good features but others are a little unneccesary. I like that it's ajax and how some things like avatars and tags are standard features which will never become "incompatible."
