Really Simple Syndication

Also known as RSS, Really Simple Syndication is a technology for keeping you updated 
on your favorite websites without the need to visit each and every one of them. 
RSS is used by computer programs that organize those updates for easy reading.

In order to use RSS, you must first have an RSS reader. There are a number of 
feed readers available on line completely free of charge. Google Reader, a Web based aggregator, capable of reading Atom and RSS feeds online or offline is such an example.

The next step is to subscribe to a feed of interest to you, and then your RSS reader
will provide you with any new content from the feed publisher. That’s all there is to it!
