I hate podcast that have a guest and where they are going to talk to each other without any further editing because it means that you are going to loose your time.

Npr have the best English podcasts of the world where they really work on them and extract their story.

Guy Raz got me first with the 'Ted radio hour' and I followed him to 'who I built this' I like also a lot 'hidden brain' and I check 'planet money'.

I got also story/documentary podcast for the entertainment but they are in French.
