Okay, folks, I'm going to call on the expertise of some of you out there to help me out here. . .and, in a way, to help me help you.

I'm kicking around the idea of doing a weekly Vikings podcast for the site.  I haven't committed completely to it yet because I want to be sure I know what I'm getting into before I say whether or not I'm definitely doing it.

I'm just wondering if any of you out there have any sort of podcasting experience.  More specifically

-How much prep time is involved?
-What sites or services would be the best to use?
-Would any of you guys listen?  (I suppose this is the most important one, now that I think about it.)
-What sort of equipment do I need?

Thanks in advance to anyone that can offer any help or insight.  If I DO decide to go through with something like this, I'll probably kick it off in early August sometime.
