RSS is a syndication standard that websites use to syndicate their content. The original acronym stood for 'Rich Site Summary'. However, that meaning has now been replaced by the major benefit of RSS which is 'Really Simple Syndication'. Most people today refer to RSS by this meaning.

RSS is just basic hypertext code like xml or html. It was first introduced by Dave Winer from www.userland.com and the Scripting News.

RSS Feeds were first used mainly by news organizations to syndicate their content. Nowadays, RSS is usually associated with blogs or blogging because Blogs use RSS Feeds to mass circulate their content. Usually, an RSS Feed will consist of Headlines and Snippets of information with links linking back to a blog or website. Some RSS Feeds contain the full body of content.

Once you are subscribed to an RSS Feed, you will be automatically updated as new information comes online. It's a very practical and convenient way to stay informed on all your different areas of interest.
