That Wikipedia article used to explain how democracy was not an example of "wisdom of the crowds"; I'm disappointed that I can't find an older revision with that segment intact.
But that said, it's important to distinguish "crowd" from "people". I've lately been trying to explain to people that the vote is the least important (while still being necessary) part of a democracy. The effort of explaining to the whole population why a certain law needs passage is the soul of democracy; votes are merely to maintain a formal record of dissent and to resolve deadlocks. They're decision making tools of last resort.
