This is the first time I've listened to this podcast, and it's a cool project. One bit of hopefully constructive criticism: you read a little too fast. This is actually a common problem in public speaking.
Thank you! I'll try to slow it down. 6b is already recorded, but I'll keep it in mind going forward.
Hopefully I'm not spamming the discussion board. Anyway, based on the highest-karma comment from the last post, I've created a trailer for the Harry Potter and the Methods of Rationality podcast.
