Where can I learn about Rss feeds and how they work?

Question

I am interested in learning how to read rss feeds.

Answer 1

A lightweight XML format for distributing news headlines and other content on the Web.

How does it work? A Web site can allow other sites to publish some of its content by creating an RSS document and registers the document with an RSS publisher. A web publisher can post a link to the rss feed so users can read the distributed content on his/her site. Syndicated contentcan can include news feeds, listings of events, stories, headlines, etc
