Really Simple Syndication (RSS) is a common XML standard for syndaicating
web content. It is typically used by content-producing sites to offer a machine-readable version of the latest headlines. For example, news sites
like CNN.com and MSNBC.com offer RSS feeds for breaking news; most blog software includes RSS support that syndicates the blogger's most recent
posts. Since its inception, RSS has radically increased in popularity; today it is hard to find a content-producing website that does not
offer at least one RSS feed.
While RSS can be used to provide a single encompassing syndication feed for a website's content, users oftentimes are interested in RSS feeds
that syndicate content catered to their specific interests. They don't necessarily want to see every article, blog post, or news item
a web site offers. Instead, a particular visitor to CNN.com might only be interested in international news, whereas another might only want to
track the latest business-related news headlines. Websites that provide specialized RSS feeds do so by offering different links for RSS feeds on
