I skimmed that this morning. Very cool stuff to see. And in a very, very small sample set of searches I do around my affiliate site I can corroborate that general information. I see niche sites near the top, some of the places like Business Insider and Spruce Eats sprinkled in, and a decent mix of retailers.
