Linking users into live social networking interactions based on the users' actions relative to similar content

A method for associating network-linked users with one another based on mutually-expressed indications of interest in device-accessible content, comprising:

• registering a user at a central user registry, the registering including recording at a non-transitory data storage medium information corresponding to an identity of the user;
• delivering to the registered user device-executable instructions configured, when executed by processing circuitry of a device network-linked, to the user registry, to enable the user to register content at a central content registry, wherein the registration of the content includes:
• storing metadata of the content at a non-transitory data storage medium of the content registry, and
• associating with the content a marker comprising coded instructions configured, when executed on a data processing device, to present to the user a graphical user interface (GUI) object which, when selected by the registered user, initiates a network link with another user;
• detecting an action of another registered user upon content having metadata;
• detecting one or more similarities between metadata of content registered by the user and the metadata of the content acted upon by the other user;
• providing an interactive, network-enabled link between the registered user and the other registered user in response to selection by the registered user of the marker displayed at a display device associated with the registered user.
