Nice! Amazon developer Alan Taylor notes they’ve added RSS via the link tag to many product category and search pages. Here’s amazon’s announcement about it, and here’s an example RSS feed I got on a book search for “weblog”.

This could be one of the first good examples of RSS making a company real money, by letting people watch a product area they are interested in and buying products as soon as they are notified of it.

update: whoa, pb drops science on exactly how this works and how to personalize it for your own associates ID.
