What is RSS?
RSS has several meanings: Really Simple Syndication, Rich Site Summary and RDF Site Summary (RDF stands for Resource Data Framework).
In any case, RSS is a method of summarizing the latest news and information from a website in a lightweight form that can be easily read by any of a number of news readers or news aggregators. The idea is to give users the ability to quickly obtain the latest news and updates from a site in a headline or news digest format. This in turn helps during high-traffic periods by reducing the load on the servers.
