Not an easy one at all, is it. I really don't envy you guys
First off, you are never going to combat sticky blindness. Regardless of the time I have read/posted, on Boards, I am as guilty as the next guy.
I often just skip the sticky section completely.
Your policy of just linking to this sticky is as good as you are going to get on this matter. If someone relatively new to Boards, or this forum in general posts a medical advice request then the divert here should help.
Second, a lot of people seem to be asking for general information on specific areas. I know that I did, when I ruptured my tendon achillies. I think that (again a sticky) explaining how to pose a question might be good. Show an example of how not to ask a question versus an acceptable means of gathering information about something.
I know that this style pushes the spirit of the rule to the limit but we have all seen areas where someones question structure makes all the difference.
I'm just not sure what we can offer people in that respect.
