RSS can be understood as a web syndication protocol that is primarily used by news websites and weblogs. RSS (pronounced "arr-ess-ess") allows a web developer to publish content on their website in a format that a computer program can easily understand and digest. This allows users to easily repackage the content on their own websites or blogs, or privately on their own computers.
RSS simply repackages the content as a list of data items, such as the date of a news story, a summary of the story and a link to it. A program known as an RSS aggregator or feed reader can then check RSS-enabled webpages for the user, and display any updated articles that it finds. This is more convenient than having the user repeatedly visit their favorite news websites, because it makes sure that the reader only sees material that they haven't seen before. Web-based RSS aggregators are also available, offering the user an alternative to using dedicated software, and making the user's feeds available on any computer with Web access.

Because RSS is understood as a term referring to many types of syndication protocols, these various RSS protocols have sometimes been accused of being "incompatible" (see The myth of RSS compatibility). Others argue that the perceived incompatibility is really a misnomer, because the underlying structure of RSS is that of XML (except for RSS 0.90) and therefore compatibility is achievable through stylesheet transformations ( XSL / XSLT), which the RSS aggregator would apply anyway in order to make the RSS feed presentable to users.
The status of RSS as of April 2004 is version 2.0.1.
