What are feeds and how do I use them?
A feed is a regularly updated summary of web content, along with links to full versions of that content. When you subscribe to a given website's feed by using a feed reader, you'll receive a summary of new content from that website. Important: you must use a Feed Reader in order to subscribe to website feeds. When you click on an RSS or Atom feed link, your browser may display a page of unformatted gobbledygook.
What are RSS and Atom?
RSS and Atom are the two feed formats. My Feed uses RSS.
Here is a page from NPR that has news and other Feed's. The page also list's Feed Reader's some are free some are not. I have been using this one RSS Reader it is free and safe.
