foursquare

Alright if your on facebook then you may have seen some of your friends posts that they have checked in somewhere it's called foursquare. Now, I'm trying to figure out the purpose of this tracking app. as I feel like I'm following a UPS package, but alas it's a real person that is being tracked.

By being on FB we are already putting ourselves out there. We have all seen the news someone posts "headed to the concert" and someone sees this knows where they live and yep they break in. So now with foursquare someone could do some major tracking and be able to figure out your daily routine know exactly where you work, workout, eat, shop, etc and before you know it you are a victim. Because not only does foursquare say you've arrived somewhere but they also supply you with a map with your said location.

What are your thoughts on this human tracking app?
