RSS (Rich Site Summary, but often referred to as Really Simple Syndication) is a web feed format used by many websites that publish frequently. It allows people to receive updates from numerous websites all in one place, by using an RSS Reader, such as Google Reader.
With RSS, you select what content you want to receive. Rather than visiting numerous websites to find new content you want to view, RSS allows you to have that new content delivered to you.
To subscribe to any of the RSS feeds, click on the feed you want, copy the URL from the address bar and paste it into your RSS application.
To view your RSS feeds, you’ll need to use an RSS Reader.
