Idea one billion on how to reduce the close vote queue:
Background
Often when I see a question with downvotes I may visit it to see "what’s up" even if I'm not interested in the specific topic in order to offer advice on improving the question or voting to close as appropriate. I find this less exhausting than reviewing from the queue as it has more of a current feel.
However not all questions that need to be closed attract downvotes (primarily duplicates, but others as well on a less frequent basis), these questions do not attract the attention from 3K+ users that they need.
Proposal
Add details on the front page/tag page as to how many close votes a question has (viewable by 3k+ users only) allowing the attention of 3k+ users who may not usually be involved with the review queue to be drawn.
Reasoning
It has been stated that the hope is to increase the number of people reviewing close votes rather than increase the number of reviews per person. This may draw in review attention from other 3K+ users increasing the number of people involved in review actions rather than leaving the burden on a small number of committed users.
Possible "leave open" button addition to the question
As Shog9♦ fairly says attracting only more close attention without attracting more "leave open" attention could lead to easier closure. As a balance to this the "leave open" button from close-vote-review could make an appearance on the question itself. This button would behave the same as the one from the queue: triggering earlier close vote aging, potentially kicking from the queue and once the question is kicked from the close-vote-queue the [n close vote]
notice being removed from the question.
