I have to admit, I am kind of jealous that they got to talk to Rob for so long. ;) When I interviewed him, we did it via email because I didn't have any fancy high-tech way to record a phone call or video chat. I'd give anything to get to talk to him for almost 3 hours! Maybe someday...
I won't spoil anything by telling you what they talk about. Go listen for yourselves. It's sooo good, and well worth the time.
