"Rumsfeld's resignation broke an internal record for the time it takes a story to go from being submitted to landing on the home page. It took about 3 minutes for users to digg the story enough for it to make it to the front door. Google News had it 20 minutes later. Lesson: 'People can break news faster than machines.'
"33% of the diggs for the Rumsfeld story happened when people saw the headline within Digg's Swarm and Stack tools."
