Has Google really been "outsmarted" by all these SEO consultants? Or is Google smarter than them, but has decided not to use their smarts? Google search is full of content farm crap, and I don't believe Googlers aren't smart enough to work out how to stop it, if they were truly motivated to do that. Maybe, someone has decided that content farm crap is better for advertising revenue than real content. Or that the "average user" would rather crap than real. Or that the expected gain in advertising revenue from improving the search is less than the cost of doing so.
