<p>I'd have to say that I don't understand why people don't answer questions using the answer section instead of the comments sections.  Your post is a good example.  Ha!</p>
<p>I think we should remove comments that answer questions, and ask users to enter these answers in the answer section, where they belong.</p>

<pre><code>@conjugateprior, could you help to add a reply, so that it could  
 benefit other people. I will mark it as answer and grant bounty  
 points. :) – Lin Ma 17 hours ago
