<p>It's my impression that on this site (and <a href="https://math.stackexchange.com/">https://math.stackexchange.com/</a>) that many times questions aren't answered but just hints in the comments are given.  (This is different on <a href="https://mathematica.stackexchange.com">https://mathematica.stackexchange.com</a> where unless it's obvious a homework problem or self-study a detailed answer is many times given.)</p>
<p>If my impression is not wrong, are there guidelines as to when to give hints as opposed to detailed answers?  If my impression is wrong, I'd like to hear about that, too.</p>
