For those interested, another enlightening paper is “Overcoming the J-shaped distribution of product reviews” by Nan Hu et al, which discusses rating biases on websites such as amazon.

This paper is downloadable from http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2369332

It seems to be a summary of their much longer 2007 paper: "Why do Online Product Reviews have a J-shaped Distribution? Overcoming Biases in Online Word-of-Mouth Communication"
