I couldn't help noticing that if you go the Amazon.com page for Isaacson's Steve Jobs bio http://www.amazon.com/Steve-Jobs-Walter-Isaacson/dp/14516485... , you see http://www.amazon.com/One-Click-Jeff-Bezos-Amazon-com/dp/159... on the first page of "Customers Who Bought This Item Also Bought" results; I couldn't help wondering if that placement is solely determined by a computer assessment of what customers also bought. But who knows, maybe it is.
