Look at this example with 11 thousand diggs
digg.com/tech_news/Digg_Unveil ...

It appears that after removing the Top Users List – Digg has chosen to remove the amount of Homepages Received from the Who Dugg This category.

Will this make Top Diggers less inclined to work so hard?????????

I can't reproduce the missing of Digg numbers on the homepage...

Key quote:
<<the amount of Homepages Received from the *Who Dugg This category*>>

Oh, I get it. It's not about the diggs on the homepage, it's about the homepages of diggers, right. The title is slightly ambiguous :)
