Suppose, as a thought experiment, you could create the ideal, perfect, social network or discussion board. Say, with 40 of the smartest, most creative, quirkiest, considerate people you knew. Hell: the 40 top exemplars of this on the whole planet. It would be a pretty awesome network.
(I know this because I accidentally created something like this, just by creating a small group with smart and interesting people in it. It really was surprisingly good.)
It can only get worse.
