Yahoo tonight dropped a new service on the world: the livestreaming service Yahoo Live. Conceptually it's very much like uStream and other livestream products. Anyone can set up a channel and embed the live player (though, oddly, not the text chat that goes with it) on their own page.
One of the really cool features of Yahoo Live is its multi-camera viewing panel. In addition to the video feed you tune in to, four other video channels -- of other users watching the same stream you are -- appear below the main video. You can jump to those channels quickly, and change the lineup of the secondary video channels by selecting names from the main video's chat window.
