Fascinating post about the validity, or lack thereof, of Amazon reviews

When it came to their attention that someone was giving them negative clicks each day, they grew dismayed. I got several emails to the email account set up in those names, asking what was going on and justifying the quality of their reviews. I responded that I didn’t like their reviews and had every right on a public Web site to give them negative votes. A few days later, ALL of my negative votes were removed from all the reviews of all the top ten reviewers, indicating to me that they complained to Amazon, which simply deleted all of my negative clicks.

More here. Very interesting.
