Earning points in game of life

Foursquare rewards users who are going places

NEW YORK — In the world of foursquare, life can be a lot like a video game: earning points and badges for places you visit and engaging in a nonphysical sort of "King of the Mountain" competition to be "mayor," or the most frequent visitor to a particular location.

Dennis Crowley, co-founder of foursquare, an online hyperlocal social service that mixes users’ current "check-in" locations and tips with gaming aspects, described the service as "a lot like Twitter but with location."
