<p>On SO, the percentage of unanswered questions is 27%. On cross validated, 39%.</p>

<p>On cross validated, there is <strong>a lot</strong> of unanswered questions. I suggest it is due to the high technical level required to answer them. I have myself huge difficulties to answer most of the questions.</p>

<p>Is there ways to decrease this percentage?</p>

<p>Should we encourage people with unanswered question to reformulate their question or to step down a level in the difficulty? Or to expand furthermore the problem?</p>

<p>Is there best practices in that cases, where you are willing to help but the questions are one step ahead of your competencies?</p>

<p>I also hope to get advice to make my questions clearer, to get response to my answers. But if these thought could help.</p>
