Where is the understanding of business in the programmers of Google?
If programmers at Google are given such free reign as publicised then that is why everyone is now feeling the pain.
If you lead a business by data (which is what Panda is) - then you have lost the plot. How can you extrapolate what are good sites from reviewers scoring into a mathematical algorithm?
That is nonsense - and that is why Google is serving crap and why webmasters are lost for answers.
