Digg is a social networking website featuring user-submitted news stories. Digg features links from across the Internet, ranging from widely known news sources to obscure blogs. Digg also builds its own list of popular stories that are going viral across the Web.
To use Digg, users submit stories, and the Digg community votes on which ones they like the best. Every story has a "Digg button," and as the story collects positive votes, the story is cross-pollinated across other channels.
