RSSWhat is RSS?:
RSS (Really Simple Syndication) is the main format used to syndicate web content primarily from news sites and blogs. Think of RSS syndication as similar to the news feeds or stock tickers that scroll along the bottom of your television screen when you watch a news channel.
Various information is gathered (in the case of blogs, new posts are gathered) then aggregated (or put together) as a feed and displayed in single location (a feed reader).
