Prediction Market for high-tech products, concepts, and trends

Yahoo! Research labs has something they call the Tech Buzz Game, it's a make believe stock market for technology trends.

You can create an account for free, and they give you $10,000 fake dollars to invest in your favorite technologies, such as ColdFusion, Flex, Flash, Java, Tiger, etc (those are some of the things that I picked).

I bet this game ends up being a fairly accurate buzz predictor/indicator...
