How about a “Vote not to close” option to counter the “Vote to close”?
A "vote to close" on an otherwise good question is like a black mark on its face.
Sometimes it will take a few weeks for a good question to close, because it takes that long for 5 silly people to find it.
So, how about an "Un-vote to close?" I mean, its a vote that cancels a close request.
This way if 5 people want to close a question, but 30 would rather it remain open, the question can remain open without supermoderator intervention.
