You listen to one, you pretty much know the rest. Siuntres is an amazing interviewer who knows his stuff. There are special episodes like the Bendis Tapes which have questions from the Jinxworld forums. These are hilarious and run often into the five hour mark. They have sprung offshoots like the Rucka Debriefing, Loeb Letters (?), etc.
If you want comic interviews, Wordballoon is where it's at. The latest was a republishing of an old Marv Wolfman interview which had me smiling ear to ear throughout.
