You know, I've read lots of posts regarding JN on this site, and I still don't understand the level of snide invective that is poured on this guy. I mean, if he designs courses that you don't like, fine. It would be too bad if the people on this site had the opportunity to talk to the man about his GCA career and a bunch of flip, abrasively-phrased questions were the best this talented, knowledgeable group could come up with. His architecture might not always be my cup of tea, but even if I don't exactly like everything he's done, he has a perspective on design and on business that would be pretty damned interesting to listen to.
That said, on the topic of architecture, I'd ask him, with all due respect, whether or not he'd ever routed a course exclusively by himself, and the degree to which he believes the routing of a course is a major determinant in the quality of the eventual course. I'd ask him the degree to which he equates the difficulty of a course with the quality of a course. I'd ask him whether he considers himself a golf architect first, or a golf businessman first.
