- Is MathJax in titles a problem? And why? 2 answers
Recently I edited a question adding LaTeX formatting for chemical formulas. I edited the both the text and the title, and this edit were accepted by peer-review. After some time, I noticed that another user (with high reputation) edited the question, eliminating LaTeX formatting from the title (with the comment NO LATEX IN TITLEZ!).
Why LaTeX formatting shouldn't be used in titles?
I think that titles, as the text, should be clean and clearly written and using LaTeX formatting will help to achieve this goal.
