Really Simple Syndication (RSS) is a format designed for sharing web content such as headlines. An RSS feed highlights fresh material for you, so you don't have to repeatedly check a site yourself for updates.
How do I use RSS?
To make use of RSS, you'll need an RSS reader, or aggregator. An RSS aggregator can be a stand-alone application, or a plug-in for another program you already use, such as Microsoft Outlook. Some web browsers, such as Firefox and Safari RSS, have RSS readers built in. There are also online aggregators, websites such as My Yahoo or Bloglines that allow you to customize them by adding RSS feeds. Find a downloadable RSS aggregator.
