1. A network-enabled content sharing and social networking system, comprising: device-executable code stored at a non-transitory data storage medium and configured, when executed by a processor, to cause a viewer device to viewably display a content-based social networking shared window graphical user interface (GUI) comprising each of a first content display portion, a second content display portion, and a linked-user portion, wherein: the second content display portion is configured with network browsing capabilities configured to access content via a data transfer network and to display the accessed content to a viewer, the first content display portion is configured to display an item of content concurrently with the second content display portion, and the linked-user portion is configured to display an identification of each linked user and a miniature image of content with which each linked-user is engaged; and a content analysis means operably coupled with the first content display portion and comprising device-executable code stored at a non-transitory data storage medium and configured, when executed by a processor, to cause the processor to identify characteristics of the content displayed to the viewer at the first content display portion, and to establish a live social network construct with a remote user, wherein: characteristics of content engaged in by the remote user via a computing device are determined by the content analysis means to be similar to the characteristics of the content presented at the first content display portion of the viewer device, the viewer device and the remote user computing device are linked via the live social network construct based at least in part upon the characteristics of content engaged in by the remote user and characteristics of content presented at the first content display portion being determined to be similar, and viewer-perceivable content in the first content display portion is shared with and rendered concurrently perceivable by the remote user at the computing device of the remote user.

The system of claim 1 , further comprising: an objectionable content-obstructing means operably coupled with the content-analysis means, and configured as a selective content filter to prevent unobstructed presentation of objectionable viewer-perceivable content at either or both of the viewer device and the remote user device.
