Over in the right column, you will see that we now have a section titled "Syndication." This has a link to our RSS/XML feed that you can receive via your favorite newsreader.
What does that mean? In short, RSS is designed to save you from having to visit dozens of websites to keep up on your favorite blogs, news sites, and the like. Instead, you use your newsreader (either a web site that you visit with your browser, or a separate application) to subscribe to those sites' RSS feeds, and read all the new stories and posts in one place.
The easiest way to get started with RSS is to get an account on theBloglines website. If you'd like to try a separate application, I can recommend AmphetaDesk, which I used when I had a Windows PC. Now that I'm on a Macintosh, I swear by NetNewsWire Lite. Both are free downloads.
One last warning on RSS feeds: they can be addicting. I have about a dozen feeds that I read every day, and about fifty more that I read when I have the time.
