There is a subtle difference between quality and trustworthiness. It's possible I missed the thread you're talking about, but as far as I can see, most of the discussions here are discussing quality. Like I said, I agree score does not correlate to quality necessarily. I was simply pointing out that in the case of specialized topics like wheels mentioned, even a score of 5 is a useful signal in telling me that it's trustworthy, versus reading a comment with a score of 1 that could be complete BS and should be taken with a grain of salt.
