Having just crossed the 2k rep milestone, I decided to help out by using the new reviewing powers someone thought to grant noobs like me. "Perhaps," I said to myself, "I can help relieve that enormous backlog of low quality posts that never seems to vanish."
Much to my surprise, most of these seem to have been reviewed, since I see comments left by high-rep people asking the author to reword the post. It seems, though, that often we get a one-time visitor who will never return to elaborate. I can't read minds, so I can't edit these to make them better. Yet they are not good enough to be accepted and cleared from the queue as-is. The third option is to delete (or vote to delete? I'm not sure how it works), but that seems a little harsh, especially as others have looked at this post and not deleted.
So, my question is: Is there anything for me to do here? Or do we just wait indefinitely for users to make posts better? Also: Is there any way to segregate posts a reviewer has commented on from those no one has seen? (Of course I expect the answer to that last one is "no," but I ask it for discussion purposes anyway.
