In order to succeed you must fail, so that you know what not to do the next time - Anthony J. D'Angelo
Facebook created “Places”, a location checkin feature for its mobile app that enabled people to share where they were. However this was linked to businesses having registered their location beforehand, and people didn’t quite take to it.
The feature was clearly launched to compete with the likes of Foursquare but it was soon removed entirely Facebook, and just integrated location checkin into status updates.
