What is RSS?
RSS (Rich Site Summary or Really Simple Syndication) is simply a Web-based newsreader-style way of keeping track of new content from some of your favorite sites. Using special reader plug-ins (you'll have to download one or install a plug-in to your browser) you can view an aggregation of headlines and blurbs from dozens of different Websites. You add these Websites as channels. Every headline, in every channel, is linked back to full article on the originating site. More details:
