RSS

What is RSS?
It lets you keep up to date on your favorite websites.
You subscribe to a rss feed, which is located at a web address.
 
This site's rss feed is located at http://www.samgreene.com/drupal_samgreene/frontpage/feed .  Click on it and see what happens!
 
You subscribe using a software called an rss feed reader.  I use google reader, but some browsers have them built in.  There are also stand alone rss feed readers.  They also come built into some mail programs (outlook has this feature).  You can get started with a search.
