What is auto-discovery?
According to the RSS Advisory Board:
Auto-discovery is a technique that makes it possible for browsers and other software to automatically find a site's RSS feed, whether it's in RSS 1.0 or RSS 2.0 format.
Supported by Mozilla Firefox 2.0, Microsoft Internet Explorer 7.0 and other browsers, auto-discovery has become the best way to inform users that a web site offers a syndication feed. When a browser loads a page and discovers that a feed is available, Firefox and Internet Explorer display the common feed icon in the address bar.
Users can click the icon to subscribe with the browser's RSS reader or the user's preferred reader. Web publishers who offer feeds reach a wider potential audience with autodiscovery.
