RSS is an acronym for Really Simple Syndication.
RSS technology allows you to subscribe to content from your favorite sites, blogs or forums. Rather than checking for updates manually, you can have the latest articles or posts delivered directly to you.
How Does RSS Work?
RSS uses what is called a "feed" to deliver updated content. Most sites have their own feeds which you can subscribe to. When new content is published, the site distributes it across the feed to all subscribers. If you subscribe to the feed, you will automatically receive the newest articles in your feed reader.
RSS is About Convenience
Many of us have favorite sites which we read on a daily basis. If you follow 
more than a few sites, the process of loading each page and checking for updates can be time consuming. In contrast, RSS brings the updates to you in one convenient location. Every update from each of your favorite sites will be sitting in your RSS reader, waiting for you.
Getting Started
To use RSS, you first need an RSS reader. There are many free options available. A popular choice is to use a a web based program such as Google Reader.
Once you have selected your reader, you are ready to subscribe to a feed. Visit the site that you are interested in, and look for an RSS subscription option. This is usually marked with the RSS feed icon:
Click on the RSS icon. On most sites you will be presented with options for subscribing to the feed. Simply select your reader and click the "Subscribe Now" button to begin receiving updates.
