A mobile Facebook feature called Find Friends Nearby, previously code-named Friendshake, is coming out of development and will soon be on its way to your iOS or Android phone. Perhaps springing from the social network’s acquisition of ambient social app Glancee, it’s still fairly primitive, merely navigating to a browser page on your device, where it will show you a list of other users within a given, undisclosed radius.
Friendshake uses your phone’s GPS to find the people around you on Facebook and easily add them as “Friends.” If you go to http://fb.com/ffn from your phone’s browser and log in to your Facebook account, you will see everybody else who is also on that page within a certain radius of you (it uses your phone’s GPS). It also reportedly works in Facebook’s iOS app by going to Menu > Apps > Find friends > Other Tools > Find Friends Nearby. Once you’re logged in you will see a screen that looks like this:
Presumably, the benefit is to let you quickly add someone in your purview like Find my Friends, although it will quite interesting to see what privacy settings are on offer.
