Geolocation on Twitter is bound to get more interesting as well. Users have been able to attach their location to each of their messages for a while now, but several new features announced on Wednesday could pit Twitter against dedicated geolocation services such as Foursquare or Gowalla.
Together with Twitter, developers are set to build a huge database of locations all over the world, called 'points of interest'. Using this database and geolocation, users will be able to reveal their exact location, as well as search for messages written from a certain location. This would pave way for searchable points of interest reviews or advertising deals with businesses.
