To podcast, or not to podcast?

I'm giving some serious thought to starting up a podcast. I think the world could use a regular show on my favorite subgenre of fantasy--sword-and-sorcery--its practitioners, and the weirdness that surrounds it.

However, I have some reservations. One is time. Another is whether anyone would listen. The third and largest is that I don't think I'm a particularly interesting person or a compelling speaker. My forte' is the written word. I'm a middle-age dad and way, way out of touch with current popular culture. I don't watch TV and the last time I may have been vaguely cool was 1992.

That said, I'm slowly formulating a plan for an interview-style show, where I would host various authors, designers, artists, and personalities to talk about themselves and their work. I think I would focus on S&S/heroic fantasy, but stray into horror, heavy metal, movies, possibly comics.

I'd love to get some input on this, yay or nay. If someone has run a podcast and could offer any encouraging words of wisdom, pitfalls to avoid, run screaming in the other direction-type advice, etc., that would be particularly helpful. Hit me up here or over e-mail.
