What is RSS?

RSS stands for Really Simple Syndication, a format for syndicating news, and/or anything that can be broken down into discrete items.  RSS is a way to distribute "What's New" for your site. News aggregators are RSS-aware programs. Many news sites and weblogs make content available in RSS format. A news aggregator helps you keep up with your favorite sites by checking their RSS feeds and displaying new items from each of them.
