RSS (Really Simple Syndication) is an XML-based format for sharing and distributing Web content, such as classified ads or news headlines. Using an RSS reader, you can view data feeds from various sources, such as OldCarOnline.com, including classifieds, headlines, summaries, links to full stories.
RSS/News Aggregators (also called Readers) will download and display RSS feeds for you. Most modern web browsers such as Internet Explorer, Firefox, Safari, Google Chrome and Opera also act as RSS readers. A number of other free and commercial News Aggregators are available for download. Many aggregators are separate, stand-alone programs – other services will let you add RSS feeds to a Web page.
Another way many people use RSS feeds is by incorporating content into weblogs, or “blogs”. Blogs are web pages comprised of usually short, frequently updated items and web links. Blogging as a publishing tool is used for many purposes: traditional journalism, personal journals, group discussions around a topic, and many combinations in-between.
