Thanks for the kind words, everyone!
Yeah, Al was wonderful, and I loved his approach to the interview. He was really chatty and open. If I asked him a question he had no problem answering it and then using it as a springboard to some other interesting topic that I hadn't even thought to ask about. He was great.
And he preferred doing it over Skype, which was both pretty cool (I got to see him face to face!) and really helpful. He could see that I was interested in what he had to say from my body language, and I was also able to tell, the same way, which topics interested him most. I've done phone interviews before, and they are good fun, but being able to see the other person--and have them see you--makes it a lot more warm.
I actually had a load of questions for him and only got to ask about 1/3 of them--I didn't want to keep him too long. But that's only because he was giving me such substantial answers that I didn't want to interrupt him.
Anyway, look for Scott Murphy next. (Fingers crossed...)
