BlurtOut

BlurtOut is a location-based social networking service where you can casually interact with people who happen to be around you. You have something in your mind and want to share it with someone. But you hesitate to post it to Facebook or Twitter because your post stays in your timeline forever and you are worried about what your friends or followers think of it. With BlurtOut, you can share your thoughts only with those around you for a specified period of time.
