Digg, reddit competitor. It seems to be doing some smart stuff behind the scences, not just relying on votes. Buoyancy (equivalent of diggs or votes in reddit) can go down as well as up.

At the heart of Newspond lies a tireless electronic brain. This highly-advanced machine intelligence continually watches over and reads hundreds of different websites, including everything from major news portals, to the tiniest blog, or forum. As a news story surfaces across one or more of these sites, Newspond notes every detail about it - from how fast a story spreads throughout the internet, to the amount of discussion surrounding the story, to even things like the rate at which people click on or bookmark the article and the size of each of the sites reporting it. Every detail is carefully noted, sized, and gauged, reading at a faster rate of speed than any human being could ever dream of. That way, you don't need to visit multiple news sites to find out what's going on.
