Description

Checkin is a verb that defines the activity of arriving at, or to indicate one's whereabouts. Foursquare describes the activity in this way:

People use foursquare to "check-in", which is a way of telling us your whereabouts. When you check-in someplace, we'll tell your friends where they can find you and recommend places to go & things to do nearby. People check-in at all kind of places - cafes, bars, restaurants, parks, homes, offices.

You'll find that as your friends use foursquare to check-in, you'll start learning more about the places they frequent. Not only is it a great way to meet up with nearby friends, but you'll also start to learn about their favorite spots and the new places they discover.

Services like Foursquare, Gowalla, and Rummble all support the notion of "checking in" to a location.
