This is fascinating Ken and, as you allude to, it is impossible to factor in people like me who delete some HPR episodes without listening to them.

Anything by Klaatu=instant listen, anything by Linux Inlaws=instant delete.

The beauty of HPR is the broad selection and unpredictability. I think the spirit of HPR would be destroyed if it became a podcast distribution service for podcasts looking to exploit HPR's ready-made audience.
