What is Foursquare?
Foursquare is social network billed as part social city guide, part friend finder, and part nightlife game. The NYC-based startup is being hailed as the next-generation social network, calling on gregarious technophiles to broadcast their locations via geo-aware mobile devices. What sets Foursquare apart from many competitors in the "local social" space is its undeniably sticky platform. Users are awarded points for their check-ins, and they scramble to earn badges and vie for bragging rights as the most frequent visitor of popular places. In short, Foursquare is fun.
I've been using Foursquare for about a week and I'm completely hooked. I can't explain it. The checking in, earning badges, and becoming mayor of this place or that—I am currently the Mayor of Starbucks. And just this morning, I stole the title of Mayor of Newhouse from another Foursquare user (and Newhouse student). The competition is fierce—but very, very fun.
Oh, and according to the linked post it has great marketing (and PR) potential. Some are even calling it the next Twitter. And hey, it's free!
