RSS, or Really Simple Syndication, is a way to get Web content (articles, images, audio, video, etc.) without having to visit the Web site that generates it. It’s a way to make content come to you instead of you coming to it.
The main benefit of RSS is that you can enjoy the Web on your own schedule; you don’t have to check and recheck your favorite Web sites for new content or worry that you’ll miss something that scrolls off the main page. Whether a site adds new content ten times a day or once a month, RSS will keep you updated.
