Every day more and more Web sites are making their content available using "web feeds". Feeds provide an easy method for creators to syndicate content and for consumers to keep up-to-date with their favourite sites without having to go to individual sites. Web feeds normally contains a short summary of content from a Web site and a link to the full article or more information. Web feeds can either be of Really Simple Syndication (RSS) or ATOM formats. Both formats are expressed in XML.
