What Is RSS?
RSS delivers you all the updates of your favorite websites to one single location. So instead of going out to all the websites you like and scouring them for new content RSS will tell you when they put new pages on their site.
This saves you time and effort and means you can keep abreast of the changes on multiple sites with very little effort.
I use Google's free RSS Reader because it is simple and slick. To get started just click the orange button to your right and then click "add to Google." Follow the instructions and you can now start using RSS.
