Why is RSS So Magical? The answer is simple: RSS is news you choose.
How Does it Work? Publishers and webmasters provide content and news in an RSS feed. Users view the content of interest in an RSS reader or news aggregator. The aggregator or reader contains the collection of feeds that are of interest to the user. As the RSS feed is updated the content in the reader or aggregator updates with the new information. At any point, users can remove a feed from their aggregator or reader and no longer receive information from that source. Ultimately, the user is choosing the news and content they wish to view.
As RSS has increased in popularity more and more webmasters and publishers have adopted RSS as an alternative communication stream. Webmasters use an RSS graphic to indicate the content is available via RSS.
