RSS, depending on whom you ask, stands for “really simple syndication” or “rich site summary.” Either way, it’s a Web-based technology that lets online publishers deliver content to readers without the subscribers even having to visit their Web sites. Publishers must like the idea, because virtually every major online publication now uses RSS to get its material into the hands of as many people as possible. (You can find PC Magazine’s RSS feeds at go.pcmag.com/rss.) And it’s not just for major publications. Most blogging services support RSS (or a similar technology called Atom), which means that you can easily stay up to date on tens of thousands of blogs without visiting their sites in the conventional manner. Podcasts—those audio programs delivered over the Internet—can also be encoded with RSS to make them easier to find.
