I often see recent questions in the review queue that on first reading should be closed mainly as not a question as they are missing a lot but they are so new that the OP has not had time to review and edit. This would also mean we appear friendlier to new users as in other meta questions there have been several questions pointing out that closing a question is often seen as unfriendly and offputting.

Could the queue be changed so that for "Not a question" at least (and possibly "non constructive" and "too localized") the queue skips them for a day or two, We have > 50k other questions to review so this would not stop people who want to review. 

Off topic and duplicates generally can't be fixed and so should be closed as soon as possible.
