really simple syndication (RSS)

Really Simple Syndication or Rich Site Summary.

A method of converting information on a website into a "feed" which can then appear on other websites or be sent in an email message.

With RSS, you do not have to visit a website to browse through the latest information to find something of interest. Instead, you read the feed, which normally provides a headline, or a headline plus a brief amount of text. To read more, you click on a link to go to the original item.
