I'm not the sort that usually overdoes it on junk food, but I have a weakness for Twizzlers. I will eat an entire bag in one sitting. I actually don't usually buy them for myself because of this.
Anyhow, regarding the interview, what sort of interview are we talking, anyhow? Email? Skype? Face-to-face? It may not be the sort of content you usually produce, but it does seem like something that would be of interest to your audience. Let me try and remember some of the advice I've been given regarding conducting interviews.
First off, research. You should know as much as possible about your subject before talking to him. You don't want to ask the same questions he's heard hundreds of times already, or blunder into a sensitive subject right at the start.
Second, try to ask open-ended questions. Don't phrase them in a way that can be answered with a simple "yes" or "no", because that's likely to be what you get. Less, "do you like TurboGrafx-16?" More, "what drew you to the TurboGrafx-16?"
A corollary to that is, assuming this is a live interaction of some sort, don't rigidly read down the line of your prepared questions. Listen carefully to your subject's answers; they very well may say something that leads to an interesting follow-up question that you didn't anticipate. Further, by showing that you're paying attention and are interested in what he has to say, you're building rapport with your subject which may allow you to touch on more sensitive topics that he wouldn't be willing to discuss otherwise.
I feel like there's something else, but it's not coming to me. This may be reiterating an earlier point, but the phrasing of your questions is important. The more thoughtfully you ask a question, the more thoughtful a response you're likely to get. It's likely to make a difference in the quality of answer you get if your subject can tell you're serious and are treating him with respect.
That's about all I can think of. Good luck if you move forward with this.
