Facebook has launched 'Facebook Places' accessible and the new Facebook iPhone application touch.facebook.com site on your moblie device. Select the Places button, find the location where you are and check-in. Just like that, the check-in will flow to your profile on Facebook.com complete with a Bing Map, a pin of your location and any commentary you’ve added to your check-in.
Places also includes the ability to see where your friends have checked in, a link to get directions to a place (via Bing Maps) and a Like button for the respective place page. The place information bubbles up to the actual Places page which has a larger map experience, plus an update for you to see all of your friends who’ve visited that location. This means you can see where your friends are checking and discover new places.
With 500 million users overnight have the ability to check-in to locations providing a wealth of information to you and your friends about businesses, common places to visit and who of your friends is going to the most random locations.
