tedster, I am starting to believe google looked at ads all along. I can see how they can factor that into there formula. For panda, they might have tweaked how they view ads and which type of ads and how many are deemed acceptable. A lot of the sites hit had 8+ ads on a page, this huge number could have gotten them pushed towards panda along with other minor factors.
