You know, I think I've finally figured out why there's never a negative review on /,, and no, it's not the "shilling." Reviews on this site are voluntary. It's not a job where you're actively employed and assigned to review something by your boss. When we're not required to do something, we usually only do things we like. So it stands to reason we only get positive reviews, because we only like to write about things we like. If the reviewer didn't like the book, he or she would probably not have the motivation to write out a full review. The trend can invert when you get into hatred territory, but let's face it, there aren't a lot of books terrible enough to write a ranty review about it.
Yes, this is not directly related to the actual review, but since there's already been one post harping on it being a /vertisement, likely the first of several, I figured I'd just post my thoughts on it.
