Really Simple Syndication (RSS) is an XML-based format for distributing and aggregating Web content (such as news headlines).Using RSS, web content providers can easily create and disseminate news headlines and URLs.
Typical applications for using RSS feeds include using a program known as a News Aggregator (also called news reader) to collect, update and display RSS feeds on another webpage. You simply plug in the addresses of the RSS files you want, such as the ones listed below. By using RSS feeds, website owners can keep websites 'fresh' and up to date.
Another way many people use RSS feeds is by incorporating content into weblogs,
or "blogs". Blogs are a publishing tool used for many purposes and consist
of web pages comprised of usually short, frequently updated items and web
links.
