The Dream is a twelve part (I think) podcast series about multi level marketing schemes I really enjoyed

Important if True was a podcast about basically anything the creators wanted to talk about and it was good and taken from us too soon

Reply All is pretty good, a little overrated, but does tell interesting stories about the internet.

Here's a weird one: Gimlet Media, the publishers of Reply All, did a podcast called The Motherhood Sessions which was basically a psychologist doing therapy with a bunch of mothers. It felt a little voyeuristic but there was something impactful about hearing psychological concepts explored with other people where you can easily make the same rational judgements as the host does, and also something very real in the stories these women would tell about their lives and how hard it is to raise their kids.
