Location-based social networks like Foursquare, Gowalla, Brightkite and Google Buzz are currently among the fastest growing new mobile services. All of these apps have one thing in common: they encourage you to share your current location with the rest of the world. By doing this, though, you are also telling people where you are not: at home. A new site, PleaseRobMe, plays on this theme and displays real-time updates from Foursquare users who broadcast their check-ins on Twitter.
