I think it would be cool if more news and magazine Websites (those which have new content each day in the form or articles) had syndication like Advogato: http://www.advogato.org/rss/articles.xml
Imagine if one could go to, say, CNN.com, and get it's site in RSS/XML--just the content and no HTML, images, etc. If I have an RSS/XML client I could download content so much faster and view in my own way, in my own style. I could download and archive for later viewing. The Net would be less congested (perhaps).
Of course, there wouls have to be some sort of money-making scheme to get it all to work...
