My first podcast is up

Okay, I took the plunge. I've signed up with a podcast host service, Liberal Syndication, and produced my first podcast yesterday (my account got a bit goofed up, so I'm posting it today). You can find episode one here. I'm still trying to figure out how this service works, whether I can post something more than just a link here (can I embed the content in the post?), etc., but for now, you can go over, listen to the show (it's about 20 minutes), grab the RSS, etc. Also, I'm open to advice as to what to do next - do I need to register with podcast promo services, etc.? All pretty new to me, but was pretty fun, and not too hard to produce (and forgive the high pitched sound in the background, I think I was too close to my computer).
