Every once in a while I publish list of podcast I listen, so you might find something interesting
I do listen podcasts literally every day - in the gym, while walking, on bus, on lunch breaks. I'd say podcasts give me about 80% of all news and help me to discover new things, not only in technology. It's a massive source of information which doesn't take dedicated time anlike books or blog posts
Some time ago I switched playback speed to 1.2x, it was a bit unusual in the beginning but brain has adopted to that quite fast and now I don't really feel any discomfort. On another hand I save 20% of the time for other episodes. I found funny effect - after this speed people seem to speak very slow :D
