<--- has come to realize that the simpsons are no longer a spoof of (north) american culture, but in fact a spoof of the very fact the people will still watch the show. the joke is not just on us, it is us.
Who cares what motivates the writers, who cares who you think they're making fun of, who cares about anything except the simple fact that this show can still make me laugh day in day out. It's entertainment people, for the masses, not for your own personal pleasure.
Maybe if all the constant detractors actually sat down and watched the show like they did when they were 10 years old, they *might* actually enjoy it again...just a thought.
