It seems that question quality declines when native english speakers go to sleep. There are many 1 rep and/or help vampire accounts that seem to hurt the overall quality of SO. I know this question has been discussed, but I have an idea that I think may help if only a little.
I propose that users below a certain rep threshold or below a certain accept ratio and rep threshold be shown links to their respective documentation libraries next to the "ask" button.
I believe that this may prevent low quality questions like this one (see original version, user has low rep and a low accept ratio) to which the answer is "Read the documentation on X [link]". this certainly won't help make questions more readable but it has the potential to preempt many "RTFM" questions which would be asked as low quality questions.
