I’ve been listening to podcasts forever. Yet it took me ages to realise that all podcast players have an option to listen at different speeds. I listen to most of my podcasts at x1.2 speed and only notice the difference when the podcast episode plays music. Same great content just a little quicker equals more time for more great podcasts.
Give it a try.
I have recently tried a few audio books and x1.5 speed seems about right as they seem to read soooo slowly.
Oh and Seth Godin has pointed to a handy video extension that does the same for video.
