FEEDBACK LOOP: A thought about Glee that's a little too long for comments--the show developed in a way unusual for network TV. The 13 episodes we just finished seeing were substantially complete and in the can by the time the second episode aired. Courtesy of the Internet, it's easier than ever for show writers to communicate with the audience outside of the show (through Twitter, blogs, and the like) and to get feedback directly from the audience. Now, at least one creator has claimed she doesn't make changes based on audience feedback, and we know of at least one incident where involvement with online fans directly got incorporated into the show. HBO also traditionally follows this model, producing a full season of episodes before airing even one.
But the question I want to ask is whether Glee is better or worse off without the feedback the audience would have provided on those first 13 episodes (though we have to assume that the network provided notes). Sure, we might have had some improvements--a quicker end to the fake pregnancy story arc, more singing and more Sue--but we might also have seen more pressure to amp up various relationships on the show, in particular the Rachel/Puck and Puck/Quinn shippers, who are quite loud.
