<p>Personally, I'm all for having the link as <span class="math-container">$\TeX$</span> is heavily used on our site and while most of the users seem to be familiar with it, it's not all, and sometimes the knowledge is partial, for example often we see people writing things like <code>$X$ ~ $N(0, 1)$</code> because they don't know the <code>\sim</code> symbol.</p>
<p>In my opinion, the best solution would be to have our own post surfacing the notation that is most commonly seen on CrossValidated.com, so related to probability, statistics, and machine learning. This would include things like <code>\sim</code>, matrices, vectors, different fonts that can be used (blackboard, boldface), subscripts and superscripts, maybe <code>\operatorname</code>, etc. The subset of the notation commonly used here seems to be much smaller than on Math.SE, so we probably could have a shorter but more focused tutorial linking to the Math.SE one for readers interested in more details.</p>
