It is sometimes hard for a person who is beginning to learn a topic to pose a question which would meet the purist's standard of "good" - but often such questions identify the stumbling blocks in understanding which many have at the same stage of learning.
If such a question attracts a good answer, that is a great thing, particularly if it meets the person who has asked the question where they are.
A question in these circumstances has the potential to help other students at the same stage in their learning, and also to help teachers to understand what is causing students a problem - and a good answer helps the teachers further (and there are a good many on the site) because the community is sharing its best insights, and we are all learning.
I upvote answers more than questions, and quite often the questions I upvote have lots of votes. But I do look out also for questions of the kind I have described, and give them a nudge upwards occasionally, because I think they form an important part of what the site is about. But I don't routinely give out such votes.
My autocorrect insists that "upvote" should really be uproot!
