Aren't Instagram photos geotagged by default? That would make Instagram essentially the "like" button for user tracking in meatspace. FB wouldn't see everywhere a user goes, but they'd know when/where the user was, when they thought something was worth a picture. And with the face-tagging stuff, they can get additional time-space data on photo subjects as well.
