The big suggestion I have for your team is to structure live sessions with television-like scheduling. Early-on, a live experience web site does not have enough usage to generate a good time for users. I learned this while running rapt.fm, a live web platform for freestyle rapping.<p>Have a calendar and use twitter or other means to announce upcoming events to concentrate the attention of users. Create well-promoted "prime time" slots, later add in regular programming, and overall make it clear to the users that all other times are "down times" and not likely to have a lot of debates going on.
