Podcasting is taking off in popularity, driven in large part because it’s extremely easy to listen to podcasts in your car. I listen to 8-9 hours of podcasts and audiobooks every week, mostly when out for my daily walks. I use the +Downcast iPhone app. I’ve been meaning to try the new Overcast app but I’ve been happy with Downcast over the years. - http://mitchwagner.tumblr.com/post...
