Google is complaining about quality. Tell us what you mean by quality, how do you determine quality.
I think G determines 'quality' by watching how visitors behave when they click on a link and go to a website on the SERPs. If the visitor's experience is...
"That was exactly what I was looking for. I'm gonna use Google search the next time I need to find something because they give me what I was looking for."
... then that is a high quality site for that query. They probably know how to spot and measure this reaction by watching the visitor's behavior (via adsense, toolbars, and dozens of other clever things).
So it is much easier for them to measure 'quality' as it happens than it is to tell us what is a 'quality' website.
When the people are happy, they come in large numbers followed by advertisers who come and advertise to all of these people. Then the advertising company known as Google makes a ton of cash.
