Query: Dr. Gwen reviews RSS Feeds for Dummies

The best part about this resource is that it assumes nothing. It takes a complete novice and explains that RSS means really simple syndication. Then it goes into the value of having changing content, the need to choose an RSS that is not only compatible with your content, but will add ever-changing, relevant content. I am using the resource to be sure that I have an accurate understanding of what it is, who it helps, how it helps, when to use one, and how to subscribe to an RSS Feed.
