On Wednesday, Facebook lauched Places, its long-rumored system to let you broadcast your real-world location to everyone in your social network; Foursquare-style. If you’d prefer to keep your location private, or at least stop your friends from posting it, Click here for instructions on how to disable it. If you’re not convinced that posting your location can be a bad thing, check out PleaseRobMe for some evidence. Of course, if you’re careful, check-ins aren’t inherently a bad thing. Whether or not you want to disable them is entirely up to you, but Facebook—yet again—has made the assumption that you want to take part in all of their privacy-eroding new features. If you don’t, or want a little more control over who can divulge your location, you can make this change pretty quickly through your privacy settings.
