There's a private group on Facebook - The Wolfe Pack - Fans of Nero Wolfe where they discuss all of these series and books, and sometimes spin off into discussions of who should play Nero and Archie in future televised series, etc.

I love listening to the unabridged audiobooks. I can't say how many I've listened to, and they weren't in order, but they're always very good. Some of them will never make it to a drama today.
