I don't think the Panda update got it right with respect to the duplicate content problem though. I still see a bunch of StackOverflow content scrapers rank as high as StackOverflow and basically link back to StackOverflow. To the same post that is ranked number 1 for that particular query. Don't have examples right away - checking my history for those instances

One site I can remember is bigresource.com which is an aggregator of sorts, it seems

The larger problem being, sites with duplicate content still rank as high as the original.
