I have opened a thread at the closed blog at the Hughniverse for subscribers to comment on this question. I will post their responses here as the weekend goes by.
If you aren’t a subscriber, you can send me an e-mail on the subject, but I am looking for very specific criticisms, linked to online back-up. My e-mail is firstname.lastname@example.org.
Or you could just subscribe, and given the content of the podcasts, the liveliness of the closed blogs there, and the original content from Lileks and Duane and Adam, that could be an early Christmas present to yourself.
