In doing research last night, I am finding a certain "house #*$!" site still wiping out wide swaths of the SERPS. Not just one page, but EVERY page all the way from 1 to 15 loaded with the same site, over and over again. 15 consecutive result pages that are 95% one site! It's mostly on the long tails, but it's pushed EVERYONE out. It's a horrible user experience and it's definition web spam in the worst way.
This rampant domain crowding renders the concept of a search engine totally useless. Bing on the other hand is listing them appropriately ALONG with all other sites, not OVER all other sites.
We're clearly seeing another Amazon / Facebook "darling site" phase with Google. Why do they do that?
Is it intentional? or can't Google handle the onslaught of millions of tagged pages?
I'd love Matt Cutts to explain the algorithmic mechanics of this one using his hands.
Are you seeing this crazy domain crowding in your vertical?
