Digg loses a third of its visitors in a month

They cite one single site for the data - compete.com. If you look at Quantcast/Alexa, neither reports that same drop.

None of these sites are accurate when used as a sole barometer. Sometimes my site looks like it has dropped off the face of the earth for a month.. then in a few weeks it goes right back to normal.
