I also listen to In our time. But maybe it is because I am not native English speaker, but I find the host quite rude to the experts, often interrupts them unnecessarily etc?
I love In Our Time. Broadcast since 1998, a podcast since 2004, over 800 episodes. And almost every single one is pure gold.
It feels like he conducts the show sort of like a stern professor at storied British school or something along those lines. Very concerned with concision and clarity. I don't tend to mind it but I can see why it would seem odd or off-putting to people.
