I agree that text formatting should be accomplished with Markdown if at all possible. Since Markdown is used across Stack Exchange, there will generally be better support for proper rendering across browsers, mobile devices, screen readers and other accessibility tools, and better compatibility with future systems. MathJax, by its nature and because it is ...

Currently, KaTeX supports a limited subset of the functionality provided by MathJax. Many of the missing functionality (notably arrays and equation alignment) is regularly used on MathOverflow, so I would not recommend using KaTeX for viewing MathOverflow. http://github.com/Khan/KaTeX/wiki/Function-Support-in-KaTeX http://docs.mathjax.org/en/latest/tex.html#...

I have enabled mathjax on the meta site. Sorry that was a slight oversight on my part.

There are alternative ways to post a short comment or answer. My shortest to date is an answer of three visible characters: https://tex.stackexchange.com/a/32692/86 I think that someone else on TeX (or meta-TeX) beat that with an answer that was two characters. The secret is invisible unicode characters. In answers, you can use entities in which case &...

I understand the sentiment to have this blacklist, but I don't think it's really important for MathOverflow to have it. Very few questions have ever had $$in their titles, and not always for actual displaymath. Here is an SEDE query to catch all extant questions which have a revision where the title contained$$. Only 10 results pop up, so I'll look at ...

It appears that XyJax is developed independently from MathJax. As a result, MathJax will not support nor test XyJax. This makes integration into MathOverflow difficult since we need to have reliable support for new features. We cannot implement such features without a suitable support plan from the XyJax developers.

MathJax v2.6 was released on Dec 30, close to the OP. These updates can lead to errors if a browser cache contains a mix of MathJax components with different versions. In that case, clearing the browser cache from all things MathJax (and for some browsers, additionally restarting the browser) should help.

The user has been contacted by a moderator. Please advise if the behavior persists.

At this point there is no MathJax support in the chat system, but this meta.MSE thread includes some information on how to overcome this issue.

An alternative is to use Benoit Schweblin's StackEdit. While StackEdit is designed for much more than just editing your MathOverflow posts, it supports essentially the same markdown+MathJax flavor as MathOverflow.

I have finished a global update on posts that contain \\{ and \\} and rebaked all of these posts. Please let me know if there are any other issues.

Here is one possible way to draw your diagram. The AMScd package doesn't seem to support longer arrows, so 7 has to make quite an detour. $\require{AMScd}$ \begin{CD} 7 @= 7 @= 7 @= 7\\ @| @. @. @AyAA\\ 7 @. @. 1 @>x>> 2 @>y>>8\\ @VxVV @. @AxAA @VxVV @VyVV\\ 6 @>x>> 5 @<y<< 4 @<x<< 3 @. 9\\ @VyVV @. @. @VyVV @...

One could make the argument that someone unfamiliar with LaTeX probably won't have the requisite background to contribute meaningfully in this site. Granted, there are some peculiarities with MathJax. But aside from that aside, here are a couple of points. The /help/formatting is fairly standard across the network (I have only seen a different version on ...

Like this: $\begin{eqnarray*} & 682 \\ -&426 \\ \hline \end{eqnarray*}$ $\begin{eqnarray*} & 682 \\ -&426 \\ \hline \end{eqnarray*}$ For general $\LaTeX$ questions see tex.stackexchange.com

I think the question is too emotionally laden to present the problem correctly. To me it is like "All the preprints use Knuth's computer modern font. How dare we change that?". The use of the word 'abuse' seems to have already not only judged the action, but tried and convicted it, and sent a summons to the executioner. A more charitable presentation ...
