RSS
What is RSS?
RSS is a family of web feed formats used to publish frequently updated pages, such as blogs or news feeds. Consumers of RSS content use special browsers called aggregators to watch for new content in dozens or even hundreds of web feeds.
RSS formats are specified in XML (a generic specification for data formats). RSS delivers its information as an XML file called an "RSS feed", "webfeed", "RSS stream", or "RSS channel". (From Wikipedia, the free encyclopedia)
