The vast majority of low-quality questions I've encountered on this site do not use $\LaTeX$ formatting. Would the site be improved if questions not containing any $\LaTeX$ were simply not allowed?
I imagine this situation: a new user writes a question, without using any $\LaTeX$. They try to submit their question, but a little textbox pops up:
It looks like you haven't used $\LaTeX$ in your question. Please use $\LaTeX$ to format your math. Use this guide if you need a reference.
This would have several positive effects:
- Greatly decreasing the share of poorly formatted posts
- Making new users familiar with $\LaTeX$
- Deterring unproductive users: are users who are unwilling to even look at the MathJax tutorial likely to contribute to the site? I think not. I understand that this might be a controversial point.
Finally, there occasionally are legitimate text-only questions that do not call for $\LaTeX$. It would still be easy to post those, all the user would have to do is nominally fulfill the $\LaTeX$ requirement, e.g. by adding
$ $ somewhere within their question.
