Digg Tracker is an extension provided by Netscape which allows you to keep tabs on what stories you and your friends are diggin.
Netscape's Digg Tracker extension helps you keep tabs on what stories your Digg friends are digging, submitting, and commenting on. A new toolbar button (shown in the preview image) features the Digg digger. When there is new activity by your friends (i.e., a new comment or a new story submission), the button will be activated and the digger will be shown with his trusty shovel.
Clicking on the activated button will open a list of your friends' activity in the sidebar, allowing you to easily browse the stories they've submitted, commented on, and dugg. Each time you view your friends' activity, you will only be shown activity that is new since the last time you opened the sidebar.
In addition, the top 5 stories from Netscape.com will be shown below your friends' activity. At any time, you can click the toolbar button to view these links, even if there is no new activity to display.
