With the change, Facebook appears to have moved Nearby Friends to a more prominent place on the front page, rather than being buried in the "More" section. Facebook is also ushering in a new feature called Wave, spotted earlier this month by Adweek and others. If you see someone in Nearby Friends, you can send a Wave to let them know you're around. Much like with a Poke, if that party is interested, they can message you back to arrange a meetup. "This is meant to give people more ways to express themselves and help friends interact with one another in new fun and lightweight ways," a Facebook spokesperson said at the time.

Despite losing the map the new tweaks mean that the Nearby Friends feature, which most folks probably don't even know exists, has gained some prominence on the social network. It's another way Facebook can make functions seen in other apps -- like Down to Lunch, in this case -- more useful because of its billion-plus user base.
