Check Out The New Facebook's 'Find Friends Nearby' Feature. It's Cool.

If you're having trouble looking up new acquaintances on Facebook, a new feature called "Find Friends Nearby" can help.
Find Friends Nearby is available on Facebook's mobile Website at fb.com/ffn , andin Facebook's mobile apps for iOS and Android. (In the sidebar, tap “Find Friends” inthe apps section, then tap “Other tools” and “Find Friends Nearby.)
When multiple people launch this feature in close proximity, they'll see each other's names in a list, even if they're not friends on Facebook. For each list entry, there's a button to quickly add that person as a friend.
To be clear, the feature only works when both parties have the Friends Near Me page open at the same time. In that sense, it's a lot different from the infamous "Girls Around Me"app, because it doesn't draw on public data, and only locates people who are actively looking for other Facebook users.
