Instagram is preparing a "Friend Map" feature.
Alessandro Paluzzi, who discovers a lot of Instagram features before they’re announced, posted an update on something he’d spotted in the app months ago: the ability to see where your friends are on a map. Snap’s Snap Map is similar, as are features built into Android and iOS. According to the images Paluzzi posted, Friend Map would be opt-in, and location data end-to-end encrypted.
