When I first read the subject, I thought you were proposing a forum for talking about dreams, as in, "Last night I dreamed that zombies invaded, but Scoble saved us with a camera that fired laser beams!"

My dream forum would be an invite-only place where only smart, rich people could attend, and we would discuss our plans for building a faraway (offworld?) utopia, free from the concerns of the rest of the world.

I'm only slightly joking.
