> Given the proven utility of prizes there should be many more of them, and yet there are not. Economically speaking, if the utility of a prize is greater than its cost, that is an arbitrage opportunity. Once enough people take advantage of that opportunity to create prizes, there will be far more prizes to choose from and the utility of the effort spent towards each prize will drop to equal its cost. A prize is somewhat like a dollar auction, but the result of any effort you bid is more random.
