Introducing A New Optional Feature Called Nearby Friends - Facebook Newsroom
"Today we are beginning to roll out a new feature called Nearby Friends that you can choose to turn on. Nearby Friends helps you discover which friends are nearby or on the go.
If you turn on Nearby Friends, you’ll occasionally be notified when friends are nearby, so you can get in touch with them and meet up. For example, when you’re headed to the movies, Nearby Friends will let you know if friends are nearby so you can see the movie together or meet up afterward…”
y’know they spend so much time saying “it’s optional” and “you can choose to turn it on” that it’s almost as if they’re definitely gonna make it mandatory at some point
