Comment by Hovercraft Full Of Eels on Add a "provide explanation to the answer" note in Help Center or FAQ

I usually leave a "canned" comment to these types of answers, something like, "I recommend that you avoid posting an answer that is mostly code with little to no explanation. The best answers fully explain a proposed solution and the rationale behind it, using code to mainly buttress and illustrate concepts mentioned in the explanation. Doing this can help elevate both question and answer so that they are more helpful to future visitors to the site who come looking for solutions to similar problems, which is, after all, the main purpose of the site.
