With RSS (Really Simple Syndication), you can easily keep track of your favorite blog, news, sports, and other websites that generate an RSS feed. Instead of having to go to your favorite website to see if there are new articles to read, those articles will automatically appear in your RSS reader (like Google Reader, Bloglines, Outlook, Apple Mail, or Firefox’s built-in RSS reader) . An RSS feed contains a summary of the article (sometimes they contain the whole article).

RSS feeds are XML files. Here is a sample RSS feed:
<xml version="1.0"?> <rss version="2.0"> <channel> <title>Title of Feed Goes Here</title> <description>Description of Feed Goes Here</description> <link>Link to the Feed Goes Here</link> <item> <title>Title of Article Goes Here</title> <description>Description of Article</description> <link>Link to Article</link> <guid>Link to Article</guid> </item> </channel> </rss>
