I've seen the following behavior several times while going through the review queue.
A new user comes along and posts a short answer to an old question (usually a comment like I'm facing the same problem).
I go to the review Queue, and start with the
Late Answersqueue, and find this answer. I flag it.
I proceed to the
First Postsqueue and see the same post. I skip it, as I have already flagged it.
I go to the
Low Quality Postsqueue and again find the same post.
What should be done when you see the same post in multiple queues? Wouldn't it be better if the same post is not shown multiple times to the same person?
