What is RSS:
RSS is an acronym for "Really Simple Syndication". Think of it as getting news bulletins or headlines from a web site. For example, the BBC has some 68 separate RSS feeds available. Because of the proliferation of RSS feeds, there is a new term called RSS Aggregators, which allow you to view RSS headlines from multiple feeds into one place, like your email inbox.
