One of the talks I went to at SWSX was by James Surowiecki on the Wisdom of Crowds. Looking into The Boat Race this weekend, (more info on Wikipedia) i find that there is a website that is using some of these principles – Inklings Markets. Sign in, and you can bet on various challenges with the fake money in your account. But it is also being used as a research tool, to look more into predictive markets.
