Please Rob Me: Drawing Attention to Risks of Location-Sharing
A site called pleaserobme.com is trying to draw attention to the dangers of location sharing, via Facebook, Twitter, Buzz, Foursquare, and other social-media updating services. The people behind Please Rob Me assert that, by telling the world where you are, you're telling potential burglars that you aren't home, and therefore they can swing by and rob your place.
The Rob Me Twitter account alerts folks when they location tweet, but it looks really spammy, and I'd probably block it if I got an @message from them and then saw that all of their messages were identical.
This is, of course, only true if the bad guys know where you live. If your friends on Facebook are robbing you, then your problem lies beyond social media, and driving around looking for empty houses is just faster, really.
I think this site is well-meaning but marginally useful: people who are into location-sharing would also be aware of the implications, and are by definition comfortable with a certain dearth of privacy.
Oh, yeah... and if I were a burglar, I'd follow these guys for an itemized list of who's not home.
