As usual, Amazon.com is leading the way in illustrating just how interactive an OPAC can and should be.

The online retailer recently added yet another feature to its product information pages: customer review comments. Now instead of only being able to post a review about a product, customers can post comments to other customers' reviews...

Some commentators are speculating that this will lead to more flame wars within the Amazon system, but with flame wars occurring there already, at least now they'll likely be contained within the comment area instead of appearing on the main product page.
