Long-form interviews can be extraordinarily good when done right. WTF with Marc Maron, CNN's The Axe Files with David Axelrod, and The Ezra Klein Show frequently hit the mark.
Very Bad Wizards is the best podcast. Period. Social psychology, moral philosophy and great banter. I own the T-shirt. Repugnant. Space Time Mind, another philosophy podcast was really picking up steam (the Transhumanist Hot Tub episode is absolutely genius) but has been silent for months.
When it comes neuroscience, Neuroscientists Talk Shop wipes the floor with the competition. Try it (the episodes with Kreizer and Canavier are two recent highlights) and then try something like Nature's Neuropod or the Brain Science podcast and decide for yourself. (That said, yesterday I discovered Brain Matters, which looks like it could be really good. Fingers crossed.)
At the end if the week, relax with BBC's Friday Night Comedy podcast The News Quiz. Sandi Toksvig left to host QI and has been gloriously replaced by Miles Jupp.
Finally technology. Leo Laporte is still king. This Week in Google is pretty much always very good. Security Now, This Week in Law and This Week in Tech can be good if the topic and panel are. Non-TWiT podcasts worth keeping an eye on include Robohub's Robots podcast, the Gillmor Gang, and of course Seminars About Long-Term Thinking.
And don't forget In Our Time.
I use the paid-for version of Podcast Addict on Android.
Please let me know about any podcasts you think I would like.
