Far too heavy on "tools" rather than "concepts". In a year, the tools all change, but the concepts remain the same. For the same price, choose Ben Hammersley's O'Reilly book. It will be 250 focused pages that will give your the perfect lay of the syndication landscape. This Wrox book rambles on for 720 pages!

The rise of blogging has caused RSS technology to become extremely important in today's computing environment. To more fully understand this subject, I took a look at Beginning RSS and Atom Programming by Danny Ayers and Andrew Wyatt (Wrox/Wiley).

This book was actually a whole lot more than I expected... As a blogger, I want to be sure the RSS feed I produce is valid and readable by newsreader clients. I just expect my newsreader to take care of things for me. But instead of just covering *how* to produce an RSS feed, the authors cover the entire spectrum of RSS technology. You get the history of RSS/RDF/Atom as well as some discussion of why they came into being. So for someone who isn't familiar with RSS at all, they'll quickly pick up all the necessary background to understand why this whole thing is critical. Then after covering the formatting of the different RSS standards, they move into consumption issues. While you may not be interested in building your own aggregator, understanding how your feeds will be used leads to a much better solution up front. Add in plenty of code examples, file snippets, and exercises to extend your knowledge, and you have a pretty complete coverage of the topic.

If you're only interested in details on building a feed, this book might not be quite as focused as you'd like. But if you're just getting into RSS from a programming perspective, this would be a good choice to give you an overall understanding.
