What is RSS? RSS (Rich Site Summary) is a format for delivering regularly changing web content. Many news-related sites, weblogs and other online publishers syndicate their content as an RSS Feed to whoever wants it.
What do I need to do to read an RSS Feed? Feed Reader or News Aggregator software allow you to grab the RSS feeds and display them for you to read and use. A variety of RSS Readers are available for different platforms.
Some popular feed readers include 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.
