For web/indie comics Gutter Talk is my go to. They interview someone different each week and find out about their processes and life in general. It'a actually where I first found out about this site.
I listen to a few gaming podcasts, one that I quite enjoy is Idle Thumbs. The hosts always seem to have a good time and review a variety of different types of game with mobile games, indie games, triple A titles and anything else, sometimes even board games.
A podcast that I've been enjoying recently that was recomended to me by a guy I work with is Scroobius Pip's Distraction Pieces. It's hosted by a spoken word poet/hip hop artist/radio host who happens to have a stutter. He interviews various guests each week, some you may have heard of, some you probably haven't. It was originaly recomended to me because he did an interview with Alan Moore (which is an episode I would recomend) but I've been enjoying his other episodes too.
That's just a few examples of what I listen to. I started listening to podcasts reglarly about a year ago because I needed something to listen to but was bored of always listening to the same music tracks over and over again Podcasts give me entertainment that changes week from week and I can also learn something from them and have a laugh from time to time while I'm at it.
