I'm not sure what I expected from an interview—after all, the part I find interesting is in hundreds of pages sitting on my desk (and, shamelessly bought from Adafruit.) It was interesting to hear the history of how the book came to be. In all, as an interview, I didn't think it was that bad ... I've seen much better interviewers, but that's not Lady Ada's forté anyhow.
What I did find a little distracting was that I perceived a bit of, for lack of a better word, flirtation—on both sides. Not like blatant 16-year-old kind of flirtation, or the kind of smitten flirtation, but more of a "gee I think you're swell but there's no way this can work" kind of thing. She had a kind of "I admire your work and desire acknowledgement from you but I'm going to try not to be an ass" and he had a kind of "if I had met an attractive, techie, intelligent woman like you 40 years ago I would have been so tongue-tied, but I'm old enough to just smile and enjoy the thought now".
Since this technical field is currently male-dominated, it's usually men interviewing other men, and without any underlying physical or sexual attraction, so everything is entirely academic. But I know how I am, and I would (and do) find it very difficult to hide my attraction if I were to interview an attractive, techie, intelligent woman. Put another way, no amount of editing could make me look anything but flirtatious if I were to interview Fried herself.
