fwiw...
RSS was new to me and I did not understand what it was at all until recently, so I've added this blurb below.
So what is an RSS feed?
An RSS feed is very much like a bulletin board. You post an article with a headline, and visitors can view and read through your articles. Often readers are encouraged to add comments to the articles. What's special about RSS is that the articles are available as a feed. This means that the readers don't have to come to you to get the latest news, you send it to them (you don't actually send anything, read on). The feed is an XML version of your articles, which can be read by RSS readers. Basically visitors to your site that use an RSS reader can subscribe to your feed by adding your feeds XML file to their readers list. Then whenever you update your feed with a new article the reader automatically gets notified. An RSS feed is also know as a Blog for those of you who have wondered what a Blog is. If this is still sounding a bit alien to you, download an RSS reader, I chose RSS reader (no reason why, just sounded straight forward) there is a good list of available readers here. Grab the URL from one of the feeds at the bottom of this page, and you'll see how it works.
