It seems that Amazon has changed their "also bought" recommendations formatting. I now get a mere 4 books as "customers also bought" recommendations when I look at a book on amazon.

 

But, I get SEVEN FUCKING PAGES of shitty, self-published "sponsored recommendations," none of which will I ever in one billion years purchase.

 

This fact, coupled with the utter unreliability of amazon's reviews, makes the amazon book page basically completely useless to me for finding additional books of interest.
