Well, people claim that digg is entirely run by the top users from what I understand, and if only 6/10 stories that make it to the front page are predicted by the top users voting patterns, theres not much to that claim right?
If you look at the top users most of them submit thousands of stories.
For example mklopez[1] submitted 16k stories were only 10% hit the frontpage and LtGenPanda[2] submitted 2,481 with a 42% popular ratio.
You can see this stats at the bottom right of the user profile on Digg.
I think nickb is still the top submitter to HN, there are about 4250 submissions from him, runner up is cwan with 3750 and then edw519 with 3180, I wonder what the top 3 on digg looks like.
