You know what,  I don't know if it will make any real difference - but the perception that top diggers have manipulated Digg have finally been responded to, according to Andy Beal at Marketing Pilgrim.

"….Kevin Rose has just announced that Digg is scrapping the Top Diggers list, believing the move will take away the perception that just a few hundred Diggers control the majority of the 5,000 submissions each day."

"…..It’s clear that Rose is reacting to the ever increasing reports that top Diggers are being approached to submit stories for money, but I’m not convinced this move will fix the problem. Whether you give the label or not, there are still many Diggers that wield a lot of power on Digg, and so, you may end up just pissing them off."

Let's see what happens.  Personally, I don't think Digg can sustain it's popularity long term.  And without doing something like this Digg would go down a lot faster, but I don't think it's going to make that much of a difference.  But maybe I'll be wrong about this one.
