RSS are used by publishers as a way of sharing content automatically. A standardized XML file publishes the information in a way that can be understood and viewed by many different applications and programmes. They are of great use to people who want to subscribe to regular updates from webistes and / or want to aggregate more than one feed in a single place. Digimind agents will automatically detect if there is an RSS feed on a page for you and will then use this format collect alerts that correspond to your query.
The advantage of knowing if there is an RSS feed on a page
If I can see there is a feed on a homepage of a website for example, I can save time. I won't need to look for the page on which I will subscribe to the feed.
Althernatively I may not want to subscribe to the RSS feed, I may only want to track other information on this site, using for example area tracker (for more information, follow this link).
