I think that our guidelines are quite clear and objective enough (however, we are always open to criticisms, if constructive of course).
Note that you almost got featured among the two posts this time. The choice was really hard this week (I got four posts for two spots) and at the end, some randomness helped me to chose ^^
It reminds me of a saying I was taught in the military: "If you can't explain what you know so a child understands, perhaps you are the one without understanding".
I would even say: it is only after having taught something, that one really masters it. At least this applies to me.
The guidelines certainly are clear and straightforward. The guidelines, along with your distilled posts give good examples of what to do to generate desirable traffic.
Actually, your statement about teaching makes sense. In the military, during training a goal what to be able to learn and perform a task without understanding it and under time constraints. The goal was to demonstrate compliance with procedures and performance under duress.
Once you demonstrate performance, "mastery" came by essentially teaching yourself. I understood the logic behind it, but only after I was done with sea duty. Different organizations different standards I guess.
