This question related to writing titles and editing posts. It is well-understood that titles should be expressive and tell about the content of the post, i.e., about the specific question being asked. Along these lines, should we encourage having latex in the title, or ASCII (or, wording) approximation?
For example, in this question, should the title be:
Show that the language of non-squares is context-free
Show that $L = {xy \mid |x| = |y|, x\neq y}$ is context-free
I'd like to know what is cs.SE policy on that?
