In an exemplary method, a content posting is received from an access device connected to a network. The content posting includes data representative of a content instance and a geographic location associated with the content instance. The content posting is stored. The content instance is selectively distributed to at least one other access device connected to the network based on the geographic location. In certain embodiments, the selective distribution includes determining that the other access device is located physically proximate to the geographic location and making the content instance accessible to the other access device in response to the determination. In certain embodiments, the method further comprises the access device creating the content instance, detecting the geographic location as a physical location of the access device, and associating the geographic location with the content instance.
