To be clear, I'm sure there are plenty of people that do, but I still think it's a minority, and I also think it's an illusion of liking them.
I've tried many times, but I just don't get the value proposition: If I'm doing something else at the same time, I would rather listen to music because anyway I won't be focused enough to not lose track of the podcast every 30 sec. If I'm fully dedicated to the podcast, well I'd rather watch it as a video or read a book.
I just feel like it tries to fit in a niche that simply doesn't exist.
To me people that like podcasts are the same that like self-improvement books. It makes you feel like you did something productive, when you actually barely listened, achieved nothing, and just had less of a good time than if I did something else.
But maybe I'm missing something.
