Can we get SmartyPants?
Some examples that have been proposed is to be able to type ``quotes'' for educated “quotes”, as well as -- and --- for en- and em-dashes.
Note this would be outside of any specialized parsing/evaluation of TeX markup as suggested in another thread. My suggestion here is to add some very light markup to use when editing the main text of the questions/answers.
Edit: I should have added that this comes from other suggestions in another thread about the look/feel of the site, and we thought it was important to stress the fact that, in this site, we do care about typography. That's why easier methods to input educated quotes and dashes should be welcomed.
Also, this should not interfere with other TeX markup, which should be probably clearly delimited by $...$
or some other kind of markers.
