Four Square, where you at?

Its funny four square used to be a game you played on the blacktop, but apparently it is much more. I have learned that now in our Social World class.
Recently I downloaded the foursquare "app" on my iphone and i was interested. This whole foursquare thing is pretty popular, i mean i wasn't expecting it.

To me it seemed worthless, like "who cares where i am at 24/7?" but really its more of a friend thing. When you check into an area, it shows if any friends of yours are there.

For instance today I checked in the gym on campus, and i saw a friend of mine checked in too, so i said hello to her. I then saw the point of four square and its uses and why it isn't creepy really, but i saw why people use it.
