I'm a little addicted to podcasts and audiobooks. According to my Stitcher app I've listened to ~2100 hours of podcasts since 2014. But I do fall asleep with one running a lot, so that's kind of inflated.
I'm starting to get into podcasts a lot more. Into the well-known stuff like This American Life and Radiolab but have been branching off into some of the other NPR ones and whatever you can find on Maximum Fun. Did you check out Cast Party last week?
I've tried, believe me, I know there's a lot of great content out there and I am missing out -- just I don't engage with it very well for some reason. I was slowly but surely making my way through The Satanic Verses in audiobook, made it through quite a bit, lost my place and just never tried again haha. I hear The Martian has a great audiobook, enjoyed the book so may try it out on that.
