<p>How about a logo like @mbq's answer <a href="https://stats.meta.stackexchange.com/questions/269/what-should-our-logo-and-site-design-look-like/459#459">wheel + check</a> but with the following differences:</p>

<ul>
<li>No check mark</li>
<li>The 'red' arc is changed to 'green'.</li>
</ul>

<p><strong>Update</strong></p>

<p>I just now noticed that mbq had posted the following logo (which follows the above idea) in the voting thread. See image below:</p>

<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<img src="https://i.stack.imgur.com/VWd3j.png" alt="alt text"></p>

<p>An interpretation of the logo would be:</p>

<ul>
<li>Questions are at the center of the wheel.</li>
<li>The arcs represent various answers with green being the one that is actually selected as the 'correct' answer as indicated by the arrow that points to it from the center.</li>
</ul>
