Diane Carey, Diane Duane, J.M. Dillard, John Vornholt, L.A. Graf, Michael Jan Friedman, Robert Greenberger and Susan Wright used to be prolific Star Trek writers but they haven't written any new Trek stories in many years. I know that Berman and Braga didn't like Diane Carey's novelization of Broken Bow, but they haven't been the showrunners in a long time. And what about the others? Does anyone know why they're no longer writing Star Trek?
