From Wikipedia: “RSS (formally “RDF Site Summary”, known colloquially as “Really Simple Syndication”) is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines or podcasts. An RSS document, which is called a “feed”, “web feed”, or “channel”, contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite websites in an automated manner that is easier than checking them manually. RSS content can be read using software called an “RSS reader”, “feed reader” or an “aggregator”. The user subscribes to a feed by entering the feed’s link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The reader checks the user’s subscribed feeds regularly for new content, downloading any updates that it finds.”
