Don't forget that the search team and AdSense team are at odds with each other most of the time, probably diametrically opposed in philosophy of what constitutes a "good site".
Correct. I received an (automated?) email from Adsense today because they noticed that I'm running less than three ad units on my pages. They recommend to add more ad units. It sounds like a bad joke after I lost 40% of my US traffic, possibly because of too many ads in the eyes of Google's search team.
