I am curious regarding the low quality answers queue. Are all posts manually reported, or is there some automated mechanism? I ask, because I see a lot of posts from regulars and established members that are either very too the point in answering the question or provide very good hints. I would hope other regulars aren't flagging them for providing help. Given that a lot of these types of posts get flagged (sorry I do not have any immediate examples to provide), is some sort of script flagging them for review based on brevity?
There is an automated script which assigns posts a "low quality answer score" which is responsible for the majority of the posts in the queue. However, flagging a post as "very low quality" should also put it in the queue.
