What exactly is "RSS"? Well, it stands for "Real
Simple Syndication" and allows users to subscribe to news feeds
such as the New York Times, the Calgary Flames, or even Harvest View
Realty, using a news reader.
What is a news reader? It is a program (also called an "aggregator") which downloads and displays news feeds. If you have the latest Thunderbird (email) or Firefox (web browser), or Apple's Safari, then you already have one, or so they tell me. Myself, I use emacs. Otherwise, there are free readers available to download for all operating systems.
How do I subscribe? Simple! Just copy the following link and then paste it into your reader's "subscribe" dialogue.
