<p>I was guilty of this behavior in one of my first replies :-).</p>

<p>As a mod, I hunt for such low-quality answers routinely (there's a tool that flags them temporarily) and I then post comments encouraging respondents to summarize or amplify.  There's no good mechanism for me to track these, though, so I don't always follow up in a timely manner.  (It's only polite to wait at least a day because not everyone visits the site all day long.)  When I do come across them again, if no change has occurred I usually downvote or vote to close, depending on how uninformative the reply has been.</p>

<p>I would love to see more high-rep community members step up and take similar actions where warranted.  <em>Very</em> few members flag or vote to close posts any more--or even downvote them, which is an excellent tool for encouraging changes in behavior.  (I figure that reflects faith in your moderators :-), but still...)  Just please remember to use such tools in a kind fashion by accompanying their use with positive, constructive comments.</p>
