This is an Internet technology that allows you to receive the latest updates from this blog on your own computer. All you need to do is register to a feed reader, such as Google Reader, Bloglines or any of the others. Clicking the "RSS Feed" link here takes you to the FeedBurner page, which gives a list of readers to choose from. Find the button for your reader, and click on it. That's it! You have subscribed to my feed. Next time you log in to your reader account, my latest posts will automatically show up there. You can also unsubscribe from any list by a single click. Saves you a lot of time, and no email spam and other hassles.

Here is a nice post of how it works.
