I really like Radiolab because they tell great stories about many topics from science to history and they do a good job at looking at things in a scientific manner. I also used to really enjoy The Joe Rogan Experience, but he tends to get too preachy and it's the same thing over and over a lot of the time. Startalk is great but Neil tends to be a bit too narcissistic for me occasionally. Don't get me wrong, I love the guy, but so does he. I will definitely check out some of the ones posted here.
