<p>I am of the opinion that we should encourage downvoters to leave a comment as to why they downvoted. This is particularly important for questions as without a comment it is hard for the OP to figure out how to improve the question. </p>

<p>If we encourage the above practice as a community norm then we will achieve several objectives:</p>

<ul>
<li>Be nice to the OP so that they do not leave the site out of frustration.</li>
<li>It increases the chances that the qn actually gets edited and improved.</li>
<li>Keep the quality of questions high.</li>
</ul>

<p>What do you think?</p>
