What is RSS

RSS stands for “Really Simple Syndication” (or “Rich Site Summary”) and is a lightweight XML format used for syndicating news and content from news-like sites, such as blogs and wikis. You can use RSS reader software (or one of a growing number of online services) to collect and monitor your favorite feeds in one place (RSS content from a publisher, viewed in one of these readers, is often called a "feed"). Wherever you see this button RSS  a source of dynamic information you can subscribe to exits.

Consumer Bottom Line: RSS makes reviewing a large number of sites in a very short time possible.

Publisher Bottom Line: RSS permits instant distribution of content updates to consumers.

RSS works by having the website authors maintain a list of notifications on their website - normally handled by the publishing application. This list of notifications is called an "RSS Feed". An RSS feed is a simple XML file designed to be viewed by an application called a "RSS reader" or "RSS aggregator" or "Newsreader". A RSS feed is a way for people to receive notification when a site is updated and to read the content of a site without having to visit it. It is a “smart pull” instead of “smart push” approach. Normally, a person would have to proactively visit the site or subscribe to get email as updates occur. RSS alerts without email. Also, RSS is unspammable because user controls own subscriptions- the site owner never has user’s contact info. It has also to do with time - people don't have the time to learn what has changed in all the sites they like to read. As such, newsreaders have become agents that work on behalf of users to eliminate the time-consuming effort to discover what's new.

Increasingly, all kinds of web sites are adding RSS feeds. Many think that the days of email newsletters are numbered because people will eventually use RSS instead. These RSS style notifications could also be used in company Intranets; pretty much anything that can be broken down into discrete items can be syndicated via RSS.
