The lack of a chatroom style interface is, what I think, makes TED less of a superficial network.
When there is a chat interface with instant messaging, many individuals don't think before they elaborate, but with this interface where you can edit and things aren't "instant messaging", then I think it creates more thoughtful and insightful answers/discussions. It also helps that most individuals in this blogoshpere seem educated or knowledgeable about many topics, and if not refer to speakers/talks from A-Z. ;)
