I am a huge fan of this show too- I agree that it breeds loyalty to the show to always have references to other episodes.  A few truly smart and creative shows are out now with this concept: Arrested Development and Curb Your Enthusiasm both come to mind.
 
Some of the most faithful viewers I know are in my department at NI.  I can't believe Fox is considering cancelling the show AGAIN.  I heard recently that Showtime might pick it up- I suppose that is reason enough to keep my digital cable for the timebeing.
