I think it's important to understand that a closed question is not necessarily in a final state, the question can be reopened after an edit which is adding more clarity to it. A question getting close votes is not a bad thing, it is an indication something needs to happen...
Just see the help center on this topic:
When should I vote to close a question?
Questions should be closed by casting close votes if:
- they are sufficiently similar to existing questions and would be answered identically to them.
- they are unclear, too broad, or otherwise problematic to identifying the problem in a way that can be properly addressed by answerers
- they are sufficiently off-topic, as outlined in the help center.
Once a question has been closed, it will no longer accept new answers and the words [on hold] will be appended to the title. After 5 days, if the question remains closed, the word [closed] will instead be appended to the title.
Closed questions can be reopened through a similar voting process that closed it. Which is the thing we should be aiming for.
If an unclear question was asked and it was voted closed in a matter of hours, the OP gets a clear message that his question is unclear. That is why it is also very much wanted to next to the close vote, we leave a comment indicating what the problem is, so the OP can react on that.
I wouldn't want us to hold off on the close votes, they are there to send a clear message, so lets accept them just as that. But don't just add a close vote, make sure that there is a comment too, indicating what needs to be changed.
