Amateurish and ersatz "thoughtful thinking aloud" is just the latest reason I can't stand listening to radio, and now prefer podcasts.
Pause and ponder all you want, Abumrad, Krulwich, Koenig et. al. I have set my player (Podcast Addict, among others) to skip silence and play at 1.2-2.0x speed, so that gormless pauses and ponderous exposition are now scarcely noticeable.
