To close a question that might be conceived to be against homework policy, or lacks clarity only 4 users need to vote to close it.
But some obscure questions might be unclear to a majority of the users, but clear to a small minority and those questions gather up close votes quickly, almost with a herd mentality. I have come across this several times, where a question is almost perfectly clear to me, but others don't understand it (out of their field) and quickly close the question before any answers are posted. This leads to frustration and loss of time from both the poster and the dedicated users of this site.
I propose to add a vote not to close in the community reasons to close a post. This will allow dissenting votes to be heard, or at least seen. This might reduce the herd mentality as it will show X people have voted to close, and Y people have voted not to close.
This would preempt the Close first, and the vote to open later process.
I believe this change will improve the experience of this community. Some of us have been active since the beta days 11 years ago and are so happy to be part of this experience, and want nothing more to welcome more and more people to be apart of [Physics.SE].
I read this meta post which claims that there is considerable inertia in the system not to change the close vote mechanics. That is understandable, but is the overall [SO] ecosystem so rigid? From a technical point of view, it would be just another reason to close, but with a negative effect on the total vote to close score. That does not seem to be a great challenge to me.
