TLDR version: Too many people can vote to close. People are overzealous when it comes to voting to close. Questions that get closed will very likely remain so because they attract little attention. This needs to be fixed.
As of last month, there are 6,279 users who can cast close votes, and the number will grow. Unfortunately, the chances of questions getting wrongfully (or not) closed will increase proportionally, since there is currently no way to counteract close votes besides voting to reopen after a question has been closed.
I think this goes against the community-driven model that SO follows. It's no longer the "Community" that can close the question; but a tiny minority of it - 5 (five) users, is all it takes. We now have the "tyranny of the minority." It is also impossible for someone to rescind their close vote even if they feel the question should no longer be closed. In the current setup, there is no way to go but down.
I know this has been suggested before, and has been ignored for unknown reasons, but it's starting to bother me. We should be able to either:
Rescind a close vote. Example: User posts a vague question. Close votes are cast. User adds sufficient detail to the question, but I can no longer rescind my vote and there are 4 close votes already. One more person comes along and votes to close. Question is closed. User gets demotivated. If it's a new user, might never come back.
Vote not to close: I disagree with the close votes being cast. I cast a vote not to close and this decreases the close vote count by some amount.
Or do both. The system as it is is broken IMHO. It was
a year ago two years ago, it's even more so today, with more users having this ability. It's apparent that a good deal of stackers support these two suggestions. But for some reason Jeff doesn't like them. Perhaps you could explain the rationale on why they shouldn't be implemented?
