Very nice. It's like irc + upvoting? It would be interesting to hear what direction you plan to take it in. Are you going to keep it as a personal project or try to build it into something like HipChat?
For now, it's just a pet project, I'm not yet sure in which direction to go. But I'm pretty sure it's not going to be like hipchat, in the sense that it will not be just a place to chat with co-workers or friends.
I would like to capture the spirit of IRC as it was in the 90's, really. A place to hangout and have mass discussions with lots of people...
Keep up the good work!
