Yes but I see he does admit something is happening with one word searches though he minimized it.
I loved the Google Dance. What a rush watching it all, like rolling the dice in extremely slow motion. When it was all over at least you knew where you stood and could look at your site/sites and see what needed to be improved.
I assume by authority sites we mean sites with lots of related links to them not sites with knowledgeable information. Maybe link bloat is the word. That would account for all the free stuff sites doing well in my topic, the really big ones get a lot of inbound links.
I am also wondering if any weighting there once was for links from edu or gov sites is gone. I wouldn't blame Google as spammers have made any value for those extensions meaningless.
