Facebook Places

Location-based apps, use GPS so people can "check in" on their mobile phones, letting friends know where they are and what they're up to.

Say you're at a bar, restaurant, coffeehouse or club. The idea is that if one of your friends sees your check-in and is nearby, they can swing by and hang out with you.
You can also leave comments and tips for friends to see.

If you like a particular dish at a restaurant, or had bad service there, you can post that info with your check-in and notify your friends.
