I don't think the system serves anyone, not users or developers. Like I said, the system was primarily an afterthought, a product of quickly cloning the iTunes Music Store into the App Store. Apple can afford to remain complacent because iOS is locked down to the App Store.
Personally, I find it fairly useful.
Developer replies are a good signal that someone's keeping an eye on feedback.
One star reviews let me see what people find annoying, and the insane ones tend to be pretty easy to filter out. Twenty people complaining about something? Signal! One "doesn't do x" in a sea of good reviews? Ignored.
