At this "social news" site the users, rather than a computer algorithm, determine how important or interesting the stories are, and Digg posts them on the homepage accordingly. The articles are tagged with number of "diggs," or thumbs-up by readers. View the tag "cloud" to see which stories are gaining traction (the headline appears bigger). And don't miss the new Digg Labs page, offering two visual alternatives to displaying the same info: one is called Swarm , the other Stack.
