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.
This is why algorithms are better than human evaluators, provided that the right humans coded them correctly. Currently we depend on Googlers getting it right. Did your physician writer copy anyone else's content (which could include his own, if online)? How was the grammar and spelling?
