RSS (Rich Site Summary) is a format for delivering regularly changing web content.
Many news-related sites, weblogs and other online publishers syndicate their content
as an RSS Feed to whoever wants it.
Why RSS? Benefits and Reasons for using RSS
RSS solves a problem for people who regularly use the web. It allows you to easily
stay informed by retrieving the latest content from the sites you are interested
in. You save time by not needing to visit each site individually. You ensure your
privacy, by not needing to join each site's email newsletter.
