You forgot a fundamental thing Digg has Google treasures. HumanPageRank power. Instead of link voting best pages, the basic formula behind Google's sucess, Digg is made up of hundreds of thousands of users who "vote" for the best content/data. I'm sure they'll utilize human voting power for something one day..
