Connections between an online system user and one or more social networking system users maintained by various social networking systems are analyzed to determine social proximity between the online system user and social networking system users connected to the online system user via a social networking system. Social networking system users connected to the online system user via each of a plurality of social networking systems are identified. Based on a number of social networking system users connected to both the online system user and to a social networking system user connected to the online system user, a social proximity score indicating relative social "closeness" of the digital magazine server user and the social networking system user connected to the digital magazine server user is generated. |
