Abstract:

The web, with its low barrier to entry and permeable social boundaries, is the ultimate medium through which to explore the finer points of the wisdom of crowds. You’re surrounded by online examples: Google’s search results. BitTorrent. The “Most E-mailed” stories on your favorite news site. Each is powered by wisdom gleaned from crowds online. You need a few things to enable online crowds to be wise.
