In a Facebook News Room post about Nearby Friends, users can choose the option to TURN the new feature ON.
If it is TURN ON, a person certainly and occasionally gets a notifications with their friends who are happen in the NEARBY locations so that you can get in touch and meet up with them.
The problem here is you are generally a homebody-type of person, this feature is not for you. As for those you keep on partying and taking outside hangouts, these are probably a good choice. Unless you always get FREE WIFIs.
