Just looked up RSS on wikpedia. and answered my own question!!
Personally I prefer the sheep pen analogy,but there you go..
RSS (which, in its most recent format, stands for "Really Simple Syndication") is a family of
web feed formats used to publish frequently updated content such as
blog entries, news headlines or
podcasts. An RSS document, which is called a "feed", "web feed", or "channel", contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite web sites in an automated manner that's easier than checking them manually.
RSS content can be read using
software called a "feed reader" or an "
aggregator." The user subscribes to a feed by entering the feed's link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The reader checks the user's subscribed feeds regularly for new content, downloading any updates that it finds.
The initials "RSS" are used to refer to the following formats:
- Really Simple Syndication (RSS 2.0)
- RDF Site Summary (RSS 1.0 and RSS 0.90)
- Rich Site Summary (RSS 0.91)
RSS formats are specified using
XML, a generic specification for the creation of data formats.
