Preferred duplicate: How about a "Vote not to close" option to counter the "Vote to close"?
What exactly happens with the new “Do Not Close”?
EDIT: I'm not talking about a 'Do not close button' in the review queue but a 'Do not close' before someone got the 5 close requests.
Couldn't we drain the close queue (currently around 50K posts in review) by adding a function that would allow to vote for 'don't close' in contrast to the actual one-way-close-only mechanism?
If someone feels annoyed by a question (although it's in accordance with the FAQ) and votes to close, someone else could think this question isn't that dump he has no chance to take countermeasures. The reversal badge has been rewarded 333 times so far and doesn't seem to do a good job in those cases.
The metrics could be 3 more close votes (majority) than don't close votes or vice versa to make it 'eligible' for the queue otherwise the question wonn't qualify for review.
