RSS stands for "Really Simple Syndication." This technology is used for distributing and gathering content from sources across the Web, such as news, magazines, and blogs. Subscribing to feeds makes it possible to review a large amount of online content in a very short time. This saves users time by not visiting sites individually, as well as not having to join email newsletters to receive information.
RSS feeds can be viewed through modern web browsers, such as Mozilla Firefox. These enabled browsers show the availability of a feed through an icon that can be clicked to “subscribe” to that specific feed which can appear on myYahoo! or iGoogle to host that feed. Also, there are standalone programs, generally referred to as newsreaders, that track and display RSS feed subscriptions, eliminating web browsers.
