There's a video-sharing ability, by which you can watch videos with other people, though your interactions are limited to a chatroom besides the video.

It's this Synthesis that I think we're seeing more and more of in the blogosphere at present as people combine blogs with other types of websites (forums, video, audio, job boards, chat rooms etc).

Setting up a live video, audio, and screen-sharing chatroom for up to 12 people at once seems like something that might require a dozen software installations and point-by-point walkthroughs.
