Sillyness. I often downvote notes because all the poster has to say is "use strict" and/or "use warning" while adding strict and/or warnings would not have helped the OP to solve his or her problem.
By all means, if code is posted which has a problem that reveals itself if strict or warnings had been used, point this out. But if a problem has nothing to do with strict and/or warning on, whining about it is just pointless clutter.
If you don't want to help someone if (s)he doesn't use strict or warnings, fine. Just keep quiet and read the next post. But it is as silly as someone not giving directions for not wearing a seat belt.
People should post code snippits. Long enough to identify the problem, but seldomly entire files. Unless it's relevant for the problem, don't post the code. Which, in most of the cases, means, don't post your 'use strict' or 'use warnings' lines. They won't matter.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
