Just in time for SXSW, Dennis Crowley, one of the original developers of Dodgeball, has released a new location-aware social app (iTunes link) for the iPhone: Foursquare. At its core, Foursquare is a location-based social network, but at the same time, it is also a nightlife game where users get extra points for being the first to visit a new place, going out every night of the week, and for adding new information about clubs and restaurants.
