RSS (Rich Site Summary) is a format for delivering regularly changing web content. Feed Reader or News Aggregator software allows you to grab the RSS feeds from various sites and displays them for you to read and use. This allows you to easily stay informed of the latest content while ensuring your privacy. RSS Readers are available on a range of platforms and include Amphetadesk (Windows, Linux, Mac), FeedReader (Windows), and NewsGator (Windows - integrates with Outlook). There are also a number of web-based feed readers available, such as My Yahoo, Bloglines, and Google Reader.
