I'm not sure you looked around well. Take a look again at new questions and see that lots of questions got upvote from musing today. Like @cryptoandcoffee has said, questions do get upvoted by musing perhaps not with an upvote ad high as that of an answer but they do. Basically questions that get upvotes from what I have noticed are well thought out questions, questions that are rare like ordinarily you won't easily find someone asking such and then questions that bothers on issues ongoing and it's genuine enough that people need answers to understand and not looking to ask questions for asking sake.

Most questions that do not get upvoted are spam questions, repetitive questions, plagiarized questions and questions which I call joke questions (they have no meaning)

Answers are more upvotes because it's easier asking questions than providing answers. Giving answers requires your intellectual ability, technicalities, research, residual knowledge, time and effort and so I think it's only fair they get more upvotes.
