I'm doing a big investigation at the moment to find out if "was this page helpful?" meaningfully correlates to quality. I do track the other interactions you mentioned, but it's difficult to map them to actionable ways to improve quality. And then even if we do make them actionable, it's hard to prove that they have actually improved quality. I'm just starting out a rigorous study of this field, though, and am hopeful that we can make advances.
