Why people not upvoting to questions is musing?

This is my opinion on why people don't vote questions for musing.

One I really don't see an upvote button for the questions. Maybe the creators wanted the comments to get more of the upvotes?

Another thing might be due to the way Quora is designed. You really don't upvote the question instead the answer. If you ever used Quora it reminds you of Musing in fact I would say Musing coped Quora aspects into its platform.

Second, people probably upvote the answers bc they helped you. You get answers and the answers get $. However I do see a flaw that answers will be more available then question with no incentive to make the question. That's just my opinion :)
