People really ought to be more concerned about these things. I'm nowhere near the quality of writer that your husband is, but I understand all too well that writers are considered disposable. It might surprise the big wigs to know that when someone stops watching, it's often because of a change in writers or because they decided to give the axe to someone who wrote really good episodes. I'd bet for every show that "jumps the shark" you'll find a change in writers.
