<p>I think it is fine to use our own judgment. One of my concerns is that the hints may be too complicated or the questioners too confused, causing them to leave and the question unanswered. It is indeed a shame.</p>

<p>I feel that the learner should decide if he/she needs more explicit hint, there is a nifty markdown called "spoiler" <code>&gt;!</code> you can use to mask the more tempting part of the answer:</p>

<blockquote class="spoiler">

</blockquote>

<p>The user will have to scroll over to see the contents. That way, we made our point as an educator, and we don't have to baby the learner and come back to check on them.</p>

<p>$\LaTeX$ codes work in this masked block as well:</p>

<blockquote class="spoiler">
  <p> $SE = \frac{SD}{\sqrt{n}}$</p>
</blockquote>

<p>Is there any function like blocking out a chunk of texts so that the questioner will know that a more explicit answer is contained, but get to decide if he/she can work on the hints (which is not blocked out) first?</p>

<p>Here is an illustration from the forum GameFAQs.com, which is very cautious about players giving out game-related spoilers:</p>

<p>The user would have to drag the cursor across the black box to reveal the more explicit part. Like the white text I revealed in this picture.</p>

<p>I feel that the learner should decide if he/she needs more than a hint. This is a Q&amp;A platform, and I hate to see most of these fundamental questions didn't get wrapped up because the questioner left or the members didn't follow up.</p>
