Not everyone likes the idea of sharing his or her exact location with the whole world, so one location-based service takes a more selective approach. Face2face pings users when a friend is nearby but doesn't disclose precise locations, letting users connect without automatically telling everyone where they are and what they're up to. "We want to look just at what's within walking distance, so oversharing doesn't ruin it," says founder Hameed Khan.
