A website or a blog creates an RSS Feed. Many Blog services automatically
create RSS Feeds. For Websites, RSS Feeds can be created manually or with software.
The RSS Feed that is created is an XML file that lives on an Internet server. There are now
hundreds of thousands of RSS Feeds sitting on Internet servers waiting patiently
for an RSS Reader to subscribe to them.
The RSS Feed Reader reads the RSS Feed file and displays it. The RSS Reader
displays only new items from the RSS Feed.
