Re: Ron Moore interview on Wired.com: answers
Yes. But so many?
And the mystery surrounding it -- they didn't make any mention that they'd left the show, to the point that fansites didn't even know if they worked on the show until season 3 had ended.
And these weren't just minor writers; Toni Graphia was the third co-executive producer, and Carla Robinson was the Story Editor. Graphia eventually went to Terminator, and later Vlaming went to Reaper (though with enough time lag that I don't know if they left FOR these shows, or got new jobs later). But Robinson didn't leave for another show, she actually hasn't written for any show since.
