> Adsense seems has nothing to do with it
All of the major "content farms" have one thing in common - they serve AdSense or other Google advertising.
They even have less "content" in common. The differences between an About.com, Answers.com, and an Ehow are profound. You can't even put them in the same category.
> Bunches of directories were whacked in this pass, not pretty.
You know - I was noticing that too. There were 2 of my favs that are no longer to be found in the top 3 pages (100 results per page)
> Can someone post a link to a penalized website?
A "penalty" can be done any old way so that you wouldn't even notice it.
If site A gets a bunch of referrals off of one keyword set (lets say, "how to xyz"), and that keyword is simply striped from all their back link anchor text before indexing - would that be a penalty? Would that even show up in someones data? Would you even know it? Could we even see it? What if the site in question got 50% of it's referrals off that keyword phrase and the thousands of descendants?
