<p>I don't necessarily have a problem with your default strategy.  However, I do want to note (as I have several times on meta), that CV is <a href="https://stats.stackexchange.com/about">intended to fulfill multiple goals</a>.  One of which is to simply help questioners get answers, and I think your strategy is likely to satisfy that goal (although, @PeterFlom's point that questioners might not be able to recognize that you provided a correct answer to a different question than the one the would have wanted to ask, if they had been able, is worth bearing in mind here).  However, another goal is to build a permanent repository of statistical information.  Here again, there is some utility to your approach, but it is clearly not as optimal as finding out exactly what the OP actually needs to know, and then providing a comprehensive, clear answer and / or pointing them to other resources where they can get the information they need.  </p>
