Why RSS? Benefits and Reasons for using RSS
What do I need to do to read an RSS Feed? RSS Feed Readers and News Aggregators
A variety of RSS Readers are available for different platforms. Some popular feed readers include Amphetadesk (Windows, Linux, Mac), FeedReader (Windows), and NewsGator (Windows - integrates with Outlook). There are also a number of web-based feed readers available. My Yahoo, Bloglines, and Google Reader are popular web-based feed readers. My personal favorite reader is Google Reader because it comes standard with EVERY gmail account. If you have Gmail, you already have Google Reader. To find it, simply log into your gmail account then type this address into your browser: http://reader.google.com
Once you have your Feed Reader, it is a matter of finding sites that syndicate content and adding their RSS feed to the list of feeds your Feed Reader checks. Many sites display a small icon with the acronyms RSS, XML, or RDF to let you know a feed is available.
