Think about that one friend of yours that uses Foursquare.  You know, the guy who whips out his phone every time you enter a new building to check in and share his location with the world.  Okay, now imagine that he’s not only checking himself in, but he’s checking you and all your friends in with him, sharing your current location against your will with all of your friends.  Yeah, that’s basically what Facebook did tonight.

Bonus scenario: your friend is very drunk, and checks in you and the boys at the strip club. Your girlfriend logs into Facebook and sees this at the top of her news feed.  Keeps getting better, right?

There really isn’t much else to say about this. It integrates with Foursquare and Gowalla, and right now it’s only accessible through the iPhone app and The only good I can see coming of this is that you can see which parties your friends are hitting up on Friday. It should be interesting to see how college students react to this as we roll back into campus this month.
