I support moving to a three close vote (if SE will allow it). The close review que has been hovering from 100-200 questions that need to be reviewed for quite sometime (at least 6 months) which means we have too many question that need to be reviewing or not enough people that review. Moving to three votes would make reviewing much more effective. I believe it is more important that questions get reviewed so that these actions can happen quickly.
There are a few other comments that I have:
If you haven't read this now would be a good time:
If we do move to a three close vote I have a reminder for those who do review.
If the question can be fixed, then edit it and make it presentable.
Help new users understand the process, many people think that closing is bad and take offense. Its good to say something on the lines of: "We need to see X and Y improvements from this question, edit it and reopen it" and help them understand the process (obviously this does not apply to questions that can't be made on topic because of their subject matter, not everyone will take the time to fix their question).
If we do move to a three close vote we will also need to step up helping people understand the process (and not being condescending) because the closing process will happen much more rapidly. Also helping new users understand the voting system is a good thing.
In addition I believe users need 3000 rep to get their question reopened (https://meta.stackexchange.com/help/reopen-questions) so we would also need people helping to get questions reopened (or flagged for reopeneing if you don't have the rep) after the question has been fixed and help people understand this process.
(EDIT: now that I think about it edits will move the question to the reopen que)
Having more good questions benefits everyone, those who want to gain rep and those who want their question answered and those who visit the site for years to come to look at the question.
