He's writing a book, the last I heard. I think it might have to deal with his career in comics and such.
I always liked Shooter. Those that called him an ass are the ones who he made actually do their jobs. Wizard actually had a good article on his tenure as Marvel's EIC. When he first came to work for the company as a regular editor, writers were handing scripts directly to artists. The editors would only get to see the finished product. He ruffled a lot of feathers by demanding to see the scripts first, then asking writers and artists to make changes (the job of an editor). His decissions led to some of the best comics of the time. Shooter was only an ass to those who didn't want to work or who thought that they knew better.
