What Is RSS?
RSS (Really Simple Syndication) is an XML-based format for sharing and distributing Web content, such as news headlines. Using an RSS reader, you can view data feeds from various news sources, such as Checkorphan.com, including headlines, summaries, links to full stories.
RSS/News Aggregators (also called Readers) will download and display RSS feeds for you. A number of free and commercial News Aggregators are available for download
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.
