I think it's important for us to process the "biggest picture presented by Google Search as a whole - including organic results, the SERP layout, and their Adwords business -- and start by accepting the [oints made above by TOI - that they are each the province of separate teams.
Why important? We people think for ourselve and can disagree. I no like TOI thinking, I do no accept that organic is separate because Google money only on ads, and always go up. When webmaster complain more, Google make more money. Why we believe Google? You always believe when big corporate say something?
When Matt Cutts and Amit Singhal speak, they are talking about the organic slice of the pie and not the overall constitution of the SERP.
We not know what they speak. Amit is Vice President on search and he know what adwords make. No doubt, because most Google money on adwords.
