I really like the idea of the site. But I think you need to differentiate yourself on the very front page by summarizing the theory there. If people think it's just a standard chat site and they don't bother to read the theory page, they'll have no reason to stick around.

Also, after I signed up with a username (and a blank password!) I was not able to see any text that I typed in the chat. Then when I came back later and tried to login as that same user, it just redirected me back to the front page of the site. When I navigated back to the chat, I wasn't logged in. This is all on Firefox 3.0.1/Linux.

Anyway, very promising. Keep on hacking!
