Since it appeared on the front page of iTunes U, it's been doing remarkable things in their chart and now sits at number 41 in their top downloads, and it's at number 2 in Duke's iTunes U top downloads. Apparently well over 2,000 people have downloaded episode 13 since last week. I suppose it's time I recorded another one. Thanks for all the encouragement, everyone!
Update (Wednesday, 16.39): NT Pod enters the iTunes U Top 40, at number 35 (iTunes U Top Downloads).
