I really enjoyed Convore on PyCon last year. Much more than Twitter for example. I remember there were rooms on just about anything, and among other things I met some guys to grab beers with on Convore. Too bad it didn't work out.
I wonder if they'd be willing to release it as open source?
The code would need a little bit of cleaning up before it could be released, but this sounds like a good idea to me. I left the company quite a while ago, so my say no longer counts, but I would be supportive if Leah and Jori decided to go down this route.
Too bad it wasn't a product that could be sold. The technology and site were cool and worked well.
