1. A format.
2. Content management tools that generate feeds in the format.
3. Aggregators and readers that subscribe to the feeds.
4. Search engines and utilities that crunch the information and ideas.
5. Services from technology companies like Microsoft and Apple.
6. Authoritative publications like the BBC, The New York Times, CNET, InfoWorld, PC World, Time, Wired, Salon, Yahoo, Reuters — that distribute news and opinion in RSS.
7. Many thousands of weblogs covering virtually every aspect of life on this planet.
8. A vast and growing community of thinkers, writers, educators, public servants, and technologists.
The revolution of RSS is what people are doing with it, what it enables, the way it works for people who use technology, the freedom it offers, and the way it makes timely information, that used to be expensive and for the select-few so inexpensive and broadly available.
RSS is the next thing in Internet and knowledge management. It’s big. A lot bigger than a format.
