<p>I find that often the "simple comment answers" are actually a solicitation for more information, at least implicitly. </p>

<p>"Seems like logistic regression would do it" is often more of the form "Is there a reason logistic regression <em>isn't</em> what you're doing?"</p>

<p>About half the time I get a comment answer, I reply with "Would you convert that to a full answer so I can upvote it?". The other half of the time however, it actually ends up prompting me to provide more information, or a reason why Profoundly Obvious Solution isn't what is going to work.</p>
