R$$ Feeds at AMZN

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.
