How do I add and watch my friends Digg activity?
Having friends on Digg is one of the greatest ways to find stories you’ll be interested in. To add a friend, visit the “Friends’ Activity” tab of your user profile and click on the “Add Friends” link on the right side of the page. There you can find friends already on Digg by importing contacts from your Web mail or desktop address book. You can also search for current Digg users by username, email, name, or location or send an email invite to people who aren’t yet on Digg. Once a friend has been added, you can track their Diggs in the “Friends’ Activity” tab of your profile. In fact, you can track of all your friends’ submissions, Diggs, and comments there.
