How many of those anonymous Amazon.com reviews are authors praising their own books? The Canada Amazon site let the truth slip out.

But even with reviewer privacy restored, many people say Amazon's pages have turned into what one writer called "a rhetorical war," where friends and family members are regularly corralled to write glowing reviews and each negative one is scrutinized for the digital fingerprints of known enemies.

One well-known writer admitted privately — and gleefully — to anonymously criticizing a more prominent novelist who he felt had unfairly reaped critical praise for years. She regularly posts responses, or at least he thinks it is her, but the elegant rebuttals of his reviews are also written from behind a pseudonym.

Well, what did you expect? These people are writers.
