(and please do not write in the comments "What is three-fourths divided by one-eighth?")
Our own Streebo is interviewing Fraction at next weekend's Heroes Convention.
Let's see if we can't come up with some good questions for him.
I often find that interviews with comics guys don't get much beyond "where do you get your ideas?" "what was the first comic book you ever read" and is working on X very different from working on Y" where X=the old book and Y=the new book. (What is with me and the math today?)
I always feel like I would be a very bad interviewer because I find coming up with questions -- new questions that the interviewee will not have pocket answers for -- difficult.
One thing I would ask is how the birth of his son has effected his comics work -- both in terms of finished products and also working habits.
Also, I would love to hear his opinion on recent comics like Final Crisis and the end of Astonishing X-Men -- and at least there you may have the virtue of a kind of new question, just because it could not have been asked before a few weeks ago.
