The feature will be in beta and presented to registered Digg users first, based on a random sampling of logged-in users. Look for the red beta flag on your Upcoming tab - this means you now have access to the Recommendation Engine. We hope to roll it out to everyone within the week or so.
The Recommendation Engine is a cool way to discover new content on Digg. Now that there are more than 16,000 stories submitted to the Upcoming section every day, itís difficult to sort through everything to find the best content. The Recommendation Engine uses your past digging activity to identify what we call Diggers Like You (who you can see on the right hand nav) to suggest stories you might like.
