adeelarshad82 writes "Facebook officially launched its 'Places' location-based product, backed by seeming rivals Foursquare and Gowalla. Facebook had been expected to announce a location service ever since it announced the press conference earlier this week. The Places service officially goes live August 19, although an iPhone app will go live on the August 18. According to Facebook chief executive Mark Zuckerberg, Facebook Places has been in development for several months. It had three goals, he said: helping share where you are in a nice and social way, to see who's around you, and just discover new and cool places to visit in the future."
