What is RSS?
RSS, sometimes known as Really Simple Syndication, is a popular means of sharing content without requiring you to constantly visit a Web site to see what's new. RSS feeds contain headlines and hyperlinks to the Web page with additional information.  If the headline interests you, just click the link from your reader.

How can I receive RSS feeds?
Desktop software applications known as “readers” or “aggregators” can collect, update and display RSS feeds from a wide variety of sources. A number of readers are available for you to download, usually at no cost. Other versions are Web and browser-based. Readers vary slightly in how they look and act, so you may find yourself testing several before settling on one.
