This question already has an answer here:
Close vote review queue grows fast! Currently it has 101.7k questions pending. My idea, based on a simple research from this answer is to introduce another queue that will partially balance the close vote queue. It should work as follows:
Questions from users with less than, let's say, 10 rep won't be shown immediately on the site. Instead they would go to a buffer, namely: Novice questions approval queue.
This queue would be presented along with other queues on the Review page, and would be available for users with, let's say, at least 2000 rep.
For each presented question, in most simple version, there would be two options: Approve and Reject (possibly also Edit & Approve).
The new queue could of course offer some gamification infrastructure: small rep rewards for reviewing for users, lets say, under 3000 rep, and analogously to other queues: badges.
If in the meantime OP would manage to earn enough rep, their question would get published automatically.
Roughly relating to these statistics if we assume that all users that were to ask "good questions" (score 3 or more) would be completely discouraged by this policy and give up asking at all, we would lost
2% of "good questions", while the Close votes queue length would be reduced by
23%. What's more important, it seems that the queue would at least grow slower then now.
Differences from First posts queue:
First posts queue handles both questions and answers. The latter do not seem a big problem on SO.
This queue would somehow shield the page and close vote queue from very low quality questions.
First post queue is based on the post being ... a first post :) This queue would work with regard to rep.
EDIT: In response to some points made in the comments&answers:
This would not prevent people from posting completely. Earning 10 rep isn't much work, and would give them right to post without review.
Any arguments in regard to gamification encouraging bad behaviour are not specific to this proposal - they describe valid problems, but in regard to the gamification idea in general.
I think that this would introduce better behaviour of the queues (instead of one Close votes queue): for example it's very easy not to approve a question by a lazy programmer, who didn't even bother to spell correctly. Such easy to review questions are currently hidden in thousands of other, more complicated cases in the Close votes queue.
two smaller problems are easier to handle than one big problem :)
