Honestly I rarely listen to podcasts that aren't audio drama type things like Nightvale and the like, I just can't be arsed listening to people rambling and laughing at their own jokes for an hour. I prefer something more structured. Some people like the sort of "chill conversational" feel, and that's cool, it's probably great for lonely people, but it's not for me.
I do watch a few youtube channels that talk about comics though.
My favourites are Comic Drake, for his solid recommendations, detailed analysis of comics and fun and creative ideas, and Strip Panel Naked for his really deep creator-focused explanations of the mechanics of how comic pages work in terms of things like layout, colour, lettering and composition.
It'd be cool to see something like those for webcomics, like with the same kind of really deep knowledge of the medium, charismatic presenter and high production values.
