What does an RSS Feed do?
RSS feeds automatically update content available without requiring users to constantly check back to the site again and again. By subscribing to an RSS feed, all new content added to the feed will be automatically and instantaneously delivered to you. Many news sites use RSS feeds to deliver headlines and brief article summaries to subscribers, for example. Some blogs also use an RSS feed to alert their subscribers when new posts are available. The FTC offers RSS feeds to update you when new press releases, speech transcripts, and other information is available.
