are any of you following the privacy concerns around foursquare? If you visit a location and check-in from that location, you become "mayor", you also alert everyone in the world via twitter that you are away from home.

foursquare is not google, so people don't care about any privacy concerns with them.
but the please rob me website does make legitimate points.
if foursquare were a Google product, there would be endless nagging about the privacy concerns of letting the entire world know exactly where you are, but since its not, people keep on happily using it.
