So here’s a definition that I found off Goggle, RSS is an acronym for Rich Site Summary, an XML format for distributing news headlines on the Web, also known as syndication. There is also a FAQ that will answer the rest of your questions. Recently, Scoble has posted a nice write up on RSS and news aggregators that should clear things up even more.
