What is RSS?
RSS means Really Simply Syndication. It is a simple XML format that allows you to share your news headlines and other web content with other sites. Basically, RSS allows you to distribute your "What's new" section to other web sites quickly and easily.
RSS is used by many popular web sites such as CNN, Forbes, Motley Fool and the BBC. Yahoo allows its users to quickly add RSS feeds to their MyYahoo service.
How does it work?
RSS (Really Simple Syndication) is the easiest way to aggregate and distribute Web content like news from your favourite website/s. RSS/XML feeds can update headlines on your computer software as they change through sections. This is possible because an RSS reader will aggregate content from your favourite preset channels and post the same in XML format on your desktop.
