Syndication feeds (RSS and Atom being two formats thereof) provide an easy way for you to keep up with the latest updates on websites to which you subscribe. All you need is a feed reader (sometimes called a "news aggregator"). This functionality is built into Firefox ("Live Bookmarks") and Internet Explorer 7, as well as any number of common "start pages" such as My Yahoo!, Google IG, and Netvibes (my favorite).

If you have any of the services listed under "Add To" below, simply click on the appropriate link to add it to your reader.

If you need the feed link itself, you can use either of these.
