The time has come. You know Digg.com has made it to the big time when other companies are writing extensions to assist Digg.
The Digg Tracker extension is used for tracking the news that your friends are "digging", submitting, and/or commenting on. Now, I understand everyone is into Digg.com, but is it feasible for an external company, especially competing with Digg to write an extension to help them? Hmmm...makes you wonder.
The extension doesn't provide enough functionality that Digg.com doesn't provide on their web site. The only thing you gain is a convenience of a sidebar. When installed, the first intro dialog box is displayed (shown below).
If you need preferences adjusted, you have that option as well on the Intro screen.
When Firefox returns, the Digg icon is displayed to the left of the address toolbar. When you receive news about your friends digging fresh news, it notifies you immediately by holding up the shovel. If there isn't enough news, it keeps its hands down.
If you click on the icon, this enables the sidebar and displays the top 5 news items your friends have "dugg", submitted, or commented on.
The only thing I would see this extension good for is the notification of fresh news through the icon at the top. The Digg Tracker extension is great for those who are die-hard Digg fans and constantly want to be updated with the freshest news and trend-setting friends, but why Netscape made it is beyond me. :-)
