Facebook is launching its own location-based application Facebook Places, backed by Foursquare and Gowalla. Facebook Places lets users share where they are and the friends they're with in real time from their mobile device.
Users have the option to share their location by 'checking in' to that place to let friends know they are there. Users that are checked-in can also see which of their friends have checked in nearby.
In addition to posting a status update, users that have checked-in can also tag friends that are with them, similar to the regular tagging function for photos on Facebook. |
