RSS is a method of distributing links to content in your web site that you'd like others to use. In other words, it's a mechanism to "syndicate" your content. RSS is mainly used for weblogs or news sites to keep readers up-to-date. The RSS feeds can be read using RSS readers such as rssreader or pluck, other readers can easily be found on the internet. The latest versions of Mozilla Firefox (by far the best browser available today), Internet Explorer 7 and Apple’s Safari have a built in RSS reader.
To add a RSS feed to your reader simply right click on the link and copy the page into the RSS reader.
