How to subscribe to an RSS feed

To subscribe to an RSS feed, you RSS reader needs the feed’s address, which is different from the address of the blog itself. The feed address for Mad Professor is madprofessor.net/index.xml. It looks like an ordinary Web address. If you enter this into you Web browser, however, you’ll probably be greeted with a page of ugly-looking code.
This is because an RSS isn’t designed to be read as a Web page, Your RSS reader knows how to translate this code into a human-readable form.
Most Web sites that offer RSS feeds publicize the fact somewhere on the home page. Unfortunately, there isn’t any one standard way to do it. Some sites have a button (often orange colored) that says “RSS” or “XML” (XML is the language RSS feeds are written in). Some have a button that looks like the one at left. Some have a text link that says “Subscribe to this site.” It’s not always easy to find a feed!
To subscribe to a feed, you can’t just click the feed link-you’ll just bring up the aforementioned ugly-looking page of code. Rightclick the link and select “Copy link location” From the pull-down menu. Then, open your RSS reader application, select the function that lets you subscribe to a feed, and paste the address into it. However, If you’re using Firefox 2.0 or later, you can configure the browser to subscribe to an RSS application when you click on a Web feed. To setup this option in Firefox, go to “Preferences” “feeds” and click “subscribe to feed using:” to choose your RSS reader application. See Page 31.
