Ok, I ran into the problem with the TeX eating my dollar sign symbols.
The use of the
$ to delimit TeX is an issue. However, Far Worse is the fact that this behavior is explained nowhere.
Furthermore, to muddy the waters even more, TeX is not enabled in the preview pane when writing or editing a question.
Therefore, formatting issues do not crop up until the question is posted, so it is likely that they will often go unnoticed.
Either TeX Needs to be enabled for the realtime editor preview, or there needs to be a very clear, succinct explanation for what will happen in the sidebar when editing or writing questions.
My suggestion would be to put it in the "How To Format" sidebar.
Also, since the delimiter is a $\$$, and people sometimes want to type just a $\$$, the information about how this is done (e.g.
$\$$) also needs to be made available.
Aaaaand TeX is not enabled on Meta. WTF?
No, wait, it is, it just took ~40 seconds to render. What the hell?
