RSS Feeds
RSS (Really Simple Syndication) provides a convenient way to syndicate
information from a variety of sources, including news stories, updates to a web
site or basically any type of publication. Regardless of the purpose for which
the RSS file is being used, by watching this XML file, you can quickly and
easily see whenever an update has occurred.
Of course, viewing the RSS feed in your web browser and hitting F5 every few
minutes is not the most efficient use of your time, so most people take
advantage of some form of client software to read and monitor RSS feeds. This
also means you don't have to waste valuable time checking if certain websites
have changed since you last looked at them; you simply let the website tell you
which lets you get on with more important things.
There are many different RSS clients available, but here are a few of the most

your RSS client.
