The Tech Buzz Game is a fantasy prediction market for high-tech products, concepts, and trendsFrom here.
As a player, your goal is to predict how popular various technologies will be in the future. Popularity or buzz is measured by Yahoo! Search frequency over time.
Predictions are made by buying virtual stock in the products or technologies you believe will succeed, and selling stock in the technologies you think will flop. In other words, you "put your play money where your mouth is."
Before registering for the contest, because of some bad experiences I have had in the past, I felt like reading their "Official Rules" for the "The Tech Buzz Game Summer 2005 Contest".
ELIGIBILITY: You must be a legal resident of the fifty United States or the District of Columbia and 13 years of age or older at the time of entry to be eligible for the prizes offered in connection with the Contest. Void in overseas U.S. territories, commonwealths and possessions, U.S. military installations located in foreign countries, and where prohibited by law.From here.
Well, it could still potentially be fun to just participate to see how many agree with how I feel about certain technologies :-)
