<p>I agree that the question isn't particularly statistical. However I would just answer these questions and if no answer is forthcoming, then point them to SO. Not voting the question up for these types of questions will help too.</p>

<p>I think it's easier to allow a wider range of questions rather than endless debating whether questions are on or off topic. </p>

<p>Also if we close questions too quickly, it can put off people returning to the site - first impressions last and all that.</p>
