Should question titles, which sometimes intentionally avoid LaTeX math for those who choose faster rendering, be edited to insist upon LaTeX math? A recent instance that prompted my question is "two tetrahedra in R^4." The original title used R^4 to mean $\mathbb{R}^4$, and it was edited, bringing a 1.5-yr-old post to the front page. I don't object to the editing—I just want to know what the community considers appropriate.
