I have a FB friend who uses FourSquare and for the life of me, I don't see why she does. Do I truly care if this FB friend who doesn't even live in my same state notifies all of her world wide friends that she is at the drugstore on the corner?

Location based security is still in its infancy. I’m sure there will be a lot more holes exposed in the coming years. I just hope there aren’t any backlash regulations that clamp down on this technology when there is an incident where someone gets hurt by their location being known.

wow i'm shocked. (kidding) why anyone uses foursquare is beyond me. i dont need to be advertised to "better" and i don't need anyone knowing where i am. i'm already tracked when i come to work, use an atm, use my cell phone, etc etc.
