I agree with you about the podcast. I listened to a few episodes and stopped listening to any of 5by5 podcasts.
In general, I have not listened to many different podcasts, but so far I felt that they were very repetitive and there was very little to gain from them. It kind of felt like I was reading a forum with debates about text editors. It is addictive, but not productive.
Aside: If anyone has a good podcast to recommend, please do.
