According to Alexa, Digg is the 190th most popular site in the world. It shows traffic holding steady for the past few months. And clicking on the pageviews tab shows that pageviews have dropped over the last year+ but not extradramatically.

(Keep in mind that the scale is logarithmic.)

As a website owner, I would love it if my site were dying like Digg.
