First of all, I need to say that I do not intend to start a controversial topic challenging the community. I'm trying to find a solution and understand the nature of MSE better to see whether it's the place I think it was or not.
In recent weeks, I have seen many questions that are so easy that can be answered by any average undergraduate student (sometimes even highschool students) taking the course in the first or the second week upvoted too many times by the community. I don't want to point fingers at any specific post, but most of these questions showed that the OP had overlooked the most basic of definitions or they did not bother to contemplate for a minute to find counter-examples to really easy and obvious problems.
I find it completely okay that people ask easy questions. After all, I ask silly questions all the time and people should never be discouraged to ask their questions, no matter how easy the question is. What I find strange is that a pattern exists in some of these questions: a user with high reputation (usually +100K) gives an answer to the question and then suddenly the question shows up in Hot Network Questions. The OP receives tens of upvotes for asking a low quality question that adds literally nothing to the website (and probably had been asked in other forms, worded differently, tens of times before) and the people who answered it receive tens of upvotes for an answer that their only effort was to type it.
The problem becomes serious when somebody, genuinely in need of help from the experts on the website, asks a really good question about a relatively advanced topic that shows real research effort, but not the kind of research that could be asked on mathoverflow. The first problem is that this kind of questions never get upvoted more than two or three times, if they get upvoted at all. Also, they're not viewed many times either, even with bounties, because many people do not have the necessary knowledge and expertise to understand and answer them. Then many users, in particular the professional mathematicians on this website, avoid answering these questions because even if you write an amazing answer, there's a high chance that your answer won't get upvoted more than twice.
This means that people who want to use MSE for advancing and widening their mathematical knowledge are left out and nobody wants to help them. We say we are not a homework website, and if you hover your mouse over the upvote button, you see "This question shows research effort; it is useful and clear", but what happens in reality is not very in line with what is said. Also, people who ask questions that are advanced undergrad level or graduate level can't go to mathoverflow because they will say that their question is not research level. So, they will get no help from stackexchange at all.
What do you think we should do about all this? How can we encourage mathematicians active on MSE to use their powers for good?
