RSSstands for "really simple syndication." It has become a common way for people to subscribe to news feeds, and is analogous to having a newspaper or magazine delivered rather than buying it at a newsstand.
RSS feeds can be viewed in your browser, loaded onto your home page if you use Google, Yahoo or similar services that provide such features, or consolidated using a number of "reader" applications.
