RSS
RSS (Rich Site Summary or Really Simple Syndication) is a means of distributing dynamic content (content syndication), using the XML format, to subscribers of that content. In order for a user to subscribe, he / she will need to sign up for a news reader aggregator (Bloglines etc.)RSS has become a popular technology for bloggers and podcasters to distribute their content, essentially 'pushing' content out to subscribers of the content rather than relying on readers to visit the site to determine if there is new content. RSS is also useful for news organizations which publish content as a matter of their business model (and update regularly). Examples include CNN and India Times. It would be useful for companies that publish news releases of newsletters for subscribers in e-mail form. While RSS does require a reader to subscribe to a news aggregator before accessing content (this may soon be bundled with the web browser which will surely impact its rate of adoption) it avoids the problem plaguing e-mail distribution of content: SPAM.
