I think musing.io emphasizes word count than the answer quality. I've seen people here write long responses that doesn't even answer the given question having higher votes while those whose answers are straight to the point and tacled the reference question having very little vote or no vote at all.
Just start browsing answers in musing, you would see a clear proof of what I'm talking about. The word count is more important to musing than the answer quality. That's why everyone is writing a very long responses on questions that requires direct short answers
