What is RSS?
RSS (Really Simple Syndication) is a format for sharing and distributing regularly updated Web content, such as news headlines and blog entries. Using an RSS reader, you can view data feeds from various information sources. RSS allows you to stay up-to-date by retrieving the latest information from the sources you're interested in, without having to visit each site individually or sign up for email newsletters.
How do I access RSS?
RSS/News aggregators (also called feed readers) will download and display RSS feeds for you. A number of 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.
