Hugh Pickens DOT Com writes: Iain Thomson reports that Facebook is adding a new application called "Nearby Friends" that alerts smartphone users when their friends are nearby. "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," says Facebook in a statement. "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." The feature, which is opt-in, allows users to select which friends get a warning that you are in the area, and prepare a subset of people who might like to know when you're near, if they have the Nearby Friends activated as well. According to Josh Constine what makes "Nearby Friends" different than competitors and could give it an advantage is that it’s centered around broadcasting proximity, not location. " If someone’s close, you’ll know, and can ping them about their precise location and meeting up. Broadcasting location is creepy so we’re less likely to share it, and can cause awkward drop-ins where someone tries to come see you when you didn’t want them to."
