This question already has an answer here:
Currently, when a question that includes MathJaX in the title is on the hot questions list found on the Stack Exchange front page, the raw MathJaX is displayed, and not the nicely formatted math.
Should this be changed, or should users just refrain from putting MathJaX in question titles?
To clarify, I'm talking about the hot network questions list found when you visit the Stack Exchange front page, not the sidebar on sites. The sidebar is a whole different issue.
