I liked this episode. There were some good perspectives from the fans. I have been listening to podcasts since 2005 I think (probably started with some podcast about the TV show Lost). Then, once Adam Carolla got his morning show, I would exclusively listen to that by podcasting it. Naturally, when he got fired and started his podcast, I began listening to that obsessievely and then branched out into other comedy podcasts.
I would like to say that focusing more on production of the shows is not necessarily a good thing. Over-production is exactly what makes most radio so much worse than podcasts. Too much thought is put into gimmicks like sound effects and contrived bits instead of substantive content. That's why I prefer conversational podcasts. From my perspective, Earwolf already has shows that seem to put a lot of planning, forethought and editing into each show. I would not like to hear more shows like The Apple Sisters for instance. I'd rather hear a show that's more about conversation and not necessarily being constantly funny and/or doing characters. The Wolfden is actually my favorite show on Earwolf.
Oh, and as far as actual audio quality goes, every show sounds great to me so I don't know that I would notice that if it improved.
