The social network on Thursday announced Nearby Friends, a
new feature built into Facebook’s mobile app that allows you to see which of
your friends are close by, and even share your exact location with others.
The new feature uses the geolocation technology in your
smart phone to determine when you are close to one of your Facebook friends.
When activated, the feature will send periodic notifications alerting you to
friends who are nearby.
Users have been able to check in on Facebook for some time,
meaning you can already share your location as part of a post, but Nearby
Friends allows you to broadcast your general location to Facebook friends
without posting at all.
