Foursquare to show users' full names, share more data

Beginning January 28, 2013, users' "full names" will be displayed across the check-in service and venue owners will have increased access to users' check-in data, the company announced in an e-mail sent to users late last night.

Foursquare's careful explanation of the new policies comes in the wake of an Instagram user revolt over new privacy policies that appeared to grant the Facebook-owned service perpetual rights to sell users' photographs without notifying or compensating the photographer.
