You know, I bet that there's people in the comic industry who miss the "good old days" when all they had to do was make and publish comic books. Now editors, writers and artists spend a lot of their time giving interviews, answering questions for comic book magazines & websites, not to mention dealing with fans and critics on the endless blogs and message boards. Fans are more involved in their comics than ever before and yet it seems that the heads of the companies listen to those fans less and less despite what they claim at conventions.
Still, I can't think of any other media (except maybe music) where so much time is spent on PR and talking about the work rather than doing it. Maybe that's why FINAL CRISIS is so late all the time.
