Borrowing from
StackExchange, it would be really useful to support
MathJax.
Examples of what is hard to do without it are:
http://mathematica.stackexchange.com/questions/14175Notice use of MathJax to typeset formulas in both the question and answers.+
MathJax allows to use LaTeX to typeset formulas of arbitrary complexity. The possible complexity of the LaTeX code actually
demands that the user sees an immediate feedback as to whether the latex code renders correctly or not. Pretty much like
the stackexchange does.
I see this would be pretty hard to do with the current use of CKEditor.
Please consider adding support for MathJax.
