Apple announced that its upcoming browser upgrade will feature RSS integration, allowing web users to use one application to view both the web and syndication feeds that are proving more and more popular among publishers. RSS, or Really Simple Syndication, is a format used for publishers to present a quick digest of updated site content. Apple's Safari program isn't the first browser to incorporate these features, as Opera has been including RSS functions for some time.
