It's a Desktop Website, a dynamic website that runs on a desktop computer. Every hour at the top of the hour it reads a list of RSS channels and stores new items from those channels in a database on your computer. You can browse those news items on the home page of your desktop website. But that's just half the story. You can also route news items into RSS channels that other people can subscribe to.
News flows in and out.
OK, let's get down to business. When a Radio user's website reads an RSS file, it sets the referer attribute of the request to this page. That leaves a clue for you that your content is important to people who use our software. You can try it too, check out the home page of this site for an explanation, or download the software to run on your desktop. Well, if MacOS X is on your horizon then I think you'll get a solution at that time, if nothing comes up sooner.
