The interview was great, but Off_trak nailed it. I'm a freelance journalist, and some of the questions gave me pause. The one about G-T allegedly "screwing [Jay] over" almost made me fall out of my chair.
My constructive criticism to you, Greg, is to be a lot more careful in crafting your questions--especially if the interview is being conducted online instead of face-to-face. There are so many ways to interpret a few of the questions maliciously that I'm surprised the interview didn't end very early on. I'm sure that wasn't your intent, but I interpreted them that way...and it appears from some of the answers you received that Mr. Wolpert interpreted them the same way. And like Off_trak said, you never want to imply your interview subject is a failure/has failed at anything unless you have facts from several well-founded sources to back up your charge. If I was to imply that one of Jay Wolpert's shows was a miserable failure to Jay Wolpert himself, I'd probably go searching for several weeks of ratings reports that show a downward trend or attempt to get a statement from someone at the network--which may be as difficult as finding a needle in a haystack when it comes to a show that aired 30 years ago, but at least you'll have that bit of information if someone does know. If I couldn't find any sources, I probably wouldn't say, "Hey, Mr. Wolpert, 'x' show got cancelled. That means it was a failure, right?"
I enjoy reading your interviews, but I'd just advise you to be a bit more careful with the questions next time. Looking forward to the next one!
