Facebook has created a new feature using your phone's GPS to speed up the process of adding friends you've just made in the real world. But the company hasn't really announced it yet.
The feature, which is called Find Friends Nearby, shows you users nearby who also have it open, using either a mobile browser or Facebook's iOS or Android apps.
To access the feature, go to the URL http://fb.com/ffn; or, on your phone's app, go to the menu sidebar, scroll down to Find Friends, and touch Find Friends Nearby.
Find Friends Nearby is clearly a great option for when you meet new people at parties, conferences or other social gatherings, making it easier for people to home in on your profile rather than wade through all the other users on Facebook who share your name.
