…we’re launching a new homepage voting experiment called Digg Trends which will surface certain highly active stories as they’re trending to Digg’s homepage so people can vote on whether or not they feel the story actually belongs there.
How Does it Work?
Digg Trends identifies and highlights upcoming stories that have a high volume of activity (think Diggs, comments, favorites, shares, etc.). When we detect a new trending story, it will appear on the homepage for ten minutes. Based on the Digg and bury activity in those ten minutes the story will either become popular or not.
In addition, they have a new Twitter account in which they tweet the trends as they occur (@Digg_Trends).
