Ok, so technically Digg users do choose homepage stories by voting up submitted links. But Digg Trends is an experiment in being a little more explicit.
Users who see the test might see a submitted story at the top of their screen. Their will be a countdown clock, showing how long until a story is set to appear on the homepage. The user can say whether or not they think the story belongs on the homepage. Here's a screenshot per the official Digg blog:
Digg has set up a Twitter account for the experiment. Follow @digg_trends to see which stories are trending.
