To Cast a Pod?

I'm pondering if I should dip my toes in the Podcasting waters. Tonight I worked up an entire 20 minute podcast and put it all together in GarageBand — including music — in about an hour. It was rather fun. But I'm not sure if I can commit to regularly taking out the time to do a podcast; unlike a text entry like this, podcasting requires a larger block of uninterrupted time (even if it might not require more time as a whole). When I'm writing a blog entry, I might be interrupted every few minutes, but if I'm recording myself, I cannot be interrupted as easily.

For that matter, I've listened to a few podcasts, and beyond the enjoyment I've gotten at putting voices to the words of the bloggers who are podcasting, I have not found myself becoming a regular listener. It is not a matter of whether the podcast was good, but I've found I simply do not have a lot of periods of time in which listening to a podcast is convenient (unlike text blogging).

Those two reasons make me think perhaps I won't publish my first (and perhaps only) stab at podcasting.
