Microsoft announced last week that the next version of their operating system, code-named Longhorn , will support RSS, or Really Simple Syndication. By integrating RSS into the operating system, users will have the ability to easily subscribe to news feeds offered by sites that make use of the RSS protocol. IE 7, Microsoft's new browser, will also integrate RSS by including a button on the toolbar which will identify sites offering RSS. Users of the Firefox browser have enjoyed this feature for several months. RSS is an increasingly popular method of receiving content online. "We want RSS everywhere, RSS is so powerful I want it in more than just the browser and the aggregator. I want it everywhere," said Internet Explorer General Manager Dean Hachamovitch. Hachamovitch says RSS is key to how people will use the Internet in the future by automatically delivering the information that is important to them. RSS provides short descriptions of web content together with links to the full versions of the content. This information is delivered as an XML file called RSS feed, webfeed, RSS stream, or RSS channel. In addition to facilitating syndication, RSS allows a website's frequent readers to track updates on the site using a news aggregator.
