I tend to see the same few characters actively use the Summit for (usually) personal conversations. Imagine 40 holograms in a circle, and two on either side were chatting about their love life. I'm not saying that's a bad thing, it's just not appropriate for the Summit imo.
What I was thinking about is this place that also has holograms, but encourages and (to a point) enforces actual debates. It would be a weekly thing, during the time most people are online, and well-advertised on the IGS a week in advance, with updates about it to encourage people. These discussions could run for an hour, and be wide and varied. The difference between this FTL channel and the Summit is that debates would be conducted in a professional setting.
It seems like it would compete with the Summit, but that's not my plan. In fact, I'm not even sure if I or someone else will make the channel.
