Without a properly formatted RSS feed, your podcast is a great idea that's stuck on a media server. This is because the podcast directories and podcast aggregators require a valid feed so the media can be indexed, browsed, and subscribed to.
The podcast uses an RSS feed, which is similar to the technology behind several popular news websites. Next time you visit a website and see a small orange icon on the right edge of the address bar, click it to view the RSS feed directly. What you'll discover is that a modern web browser can quickly sift and sort the information on the page.
