Amazon Adds Wikis to Product Pages?

In what I’m assuming is a limited beta launch, I stumbled across a very simple wiki embedded in the product pages on Amazon tonight. It is a great idea and I’m very curious how it will turn out, the LA TImes short-lived wiki experiment was a complete disaster (have to give them credit for trying though!). I’d say if anybody can take a wiki mainstream, Wikipedia has probably come the closest so far, Amazon would be one that I’d be willing to put money on.
