What is RSS?
RSS (Rich Site Summary) is a format for delivering regularly changing web content. Many news-related sites, weblogs and other online publishers syndicate their content as an RSS Feed to whoever wants it.
What do I need to do to read an RSS Feed?
RSS Feed Readers and News Aggregator software allow you to grab the RSS feeds from various sites and display them for you to read and use. A variety of RSS Readers are available for different platforms. Once you have your Feed Reader, you simply add this link to your RSS feed. Many sites display a small icon with the acronyms RSS, XML, or RDF to let you know a feed is available.
