I never really saw the point. I suppose if you have a high friend density in your location, it might be more useful. On a college campus, for instance. If your friends and coworkers are widely scattered through several towns, so even if you post your location nobody's likely to be nearby, then it's really kinda pointless. It seems like this would be a good candidate for a peer-to-peer implementation. Send the data directly to your friends' devices, without a central repository or way for other people to check. Of course, then you probably lose many of the marketing possibilities.
