What is a RSS Feed? I see "RSS", "XML", and "Atom" out there, but I don't know how I might use these links when I find them.
Feeds are a way for websites large and small to distribute their content well beyond just visitors using browsers. Feeds permit subscription to regular updates, delivered automatically via a web portal, news reader, or in some cases good old email.
Why is This a Good Thing? Technology evolution in online publishing has made it really easy to not only publish regular updates to web-based content, but also keep track of a large number of your favorite websites or blogs, without having to remember to check each site manually or clutter your email inbox.
Bottom Line: Subscribing to feeds makes it possible to review a large amount of online content in a very short time.
