Rated 3 out of 5 stars
I like the idea behind this extension, but the biggest problem I have with it is that it slows down my browser. I even have a pretty fast computer and OS, but it really slows browsing.
There are a few other things about it that could stand improvement, too. It should open the Digg submission page in a new tab/window. It should start the submission at step 1, not 2, so that the media type can be selected. And it should try to submit the URL and other information to Digg automatically, leaving less for the user to fill in. Those are minor problems, though.
If this extension ran faster or my computer was very, very fast, I would continue to use it.
Also, I see another user didn't like the extension's button in the status bar. I like it in the status bar. It's a great place for it, since I can't live without status (gotta see where the links take me to!), but having the option of placing it in a tool bar would be very good.
