Bruce - PLEASE let the guests talk!
Is there one specific episode you have in mind... that I didn't let the guest speak enough?
I was just listening to #16 this morning -- at the half way mark I thought: I don't know anything about this guest!
If it's an interview, I would think the majority of what you say should be questions of the guest.
Get yourself a copy of this - it really is superb:

OT: If no one else has suggested it, you need to get Nefario on.
