Facebook, the largest social network in the world with more than half a billion users, has launched a location-enabled service element that lets smartphone users publicise their whereabouts through the site. Users can also tag friends who are with them, and locate other friends that may be nearby. The service chimes with many of the location-based service concepts touted within the mobile industry when LBS first rose to prominence a decade or more ago.
The service is only available in the US to begin with, and only to iPhone users who will need to download an updated version of the Facebook iPhone application in order to access the new service. Facebook said it will look to offer the service in more countries and on more platforms soon.
