Combining fast food with social gaming is fascinating, particularly giving restaurant credit as a measure of successful burger ideas. The Bits Blog explains 4Food:
Here’s how it works: I create a burger, call it “The Bits Burger” and broadcast it to Twitter or Facebook. Each time someone orders my special creation, I get 25 cents credit in the restaurant and my burger rises up the leaderboard. The more customers order my burger, the higher it goes and the more credits I get, until I’m eating free.
