I agree about content quality but for the human readers not for machines.
It also depends which readers read this content.
Content quality: What is considered good quality to some people doesn't necessarily have a value for others, and vise versa. (see the violinist example)
Once upon a time, I hired a physician to write on one of my blogs. He wrote super good.. but it was mainly written to the eyes of medical scientists and not for the average people who wanted answers to simple medical questions. It require hard time to digest and understand his material but somehow people cope with it.
Needless to say that this blog was kicked severely by Panda.
If search engines know-how to personalize searches, they will make a great progress.
