Some folks are seeing a new, Places-based, checkin-focused module on Facebook. “Popular Places†shows locations at which friends in your network frequently check in. It appears for some users on the right column of the web interface, where you might normally see events, advertisements or the increasingly irrelevant “poke†list. Ideally, this new feature could help you find interesting, personally relevant destinations in your area. It will also be one of the first ways Facebook (Facebook) is singling out and surfacing checkins aside from having them appear in the news feed.
