RSS : how to deliver your content to thousands of suscribers ?

Originally developed by Netscape, RSS (which is a short for RDF Site Summary or Rich Site Summary is an XML format for syndicating Web content.

A Web site that wants to allow other sites to publish some of its content creates an RSS document and registers the document with an RSS publisher. A user that can read RSS-distributed content can use the content on a different site. Syndicated content includes such data as news feeds, events listings, news stories, headlines, project updates, excerpts from discussion forums or even corporate information.
