RSS Feeds
RSS stands for Really Simple Syndication.
Also called web feeds, RSS is a content delivery vehicle. It is the format used when you want to syndicate news and other web content. When it distributes the content it is called a feed. RSS Feeds allows ones to create a content on one location and have that content to be diffused to many places. For instance you could integrate my blog post with in an area of your own website by using a feed reader. Or you can also follow my blog for new posts by subscribing to my RSS feed within a feed reader software or service such as your iPhone or desktop feed reader or using Google Reader and see new posts directly on your customize Google homepage / iGoogle.
