Questioners often ask how they can tinker with typography (particularly in math mode, particularly white space). In many cases the best answer is "Please don't - the defaults have been carefully chosen to implement proven best practices." Here's an example, with a comment to that effect, and a good response from the OP: Is there a way to define single space or more in math mode to be \,?.
Should this site have a standard polite response to post for those questions?
