Fantastic podcast as usual - especially interesting for me as I got into manga from webcomics!
I'm always a little torn on the format, as I prefer the pace of print - when I [re]discovered print comics (saying that makes me sound like I lived under a rock until 2006
) I shyed away from webcomics for a while, deciding I prefered occasional big chunks of comic than a slow dribble. But this opinion changed once I started using the mighty Google Reader, and I get a daily dose of comic without having to worry about when and how often the various stories update.
I was surprised that nobody mentioned Questionable Content. I've been reading it for a couple of years now, and think it's a very good example of how webcomics should be done, or at least how they can be done well.
