Now I know this must sound like some match made in Web 2.0 hell, but stick with me because it really is a pretty nice tool if you enjoy the popular social news Web site, digg.com.
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.
