I agree that really good ideas can come out of discussion and interaction with other people -- but I think this works best with 1-3 other people. With a small group, you can have a productive conversation that successfully identifies and solves the problems in an idea. But the least effective group brain-storming sessions are ones with a large number of people, and those are also the ones that are worst for introverts. With too large a group you end up with a reluctant high school English class socratic seminar.
