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 ...

This MathJax tutorial contains instructions for commutative diagrams. That should be enough for basic drawings of this type. You might also want to check out the MO FAQ post Best way to post graphics to MO. This post assumes that you already have the image file. Pretty diagrams are nice, but would advice against spending too much time polishing graphics as ...

Both systems of capitalization are OK for use here: How to Answer Questions on MO. How to answer questions on MO. Conclusions: Which system should you use? The one most comfortable to you. Should you change someone else's post from one system to the other? No. Should you complain if someone else changes your post from one system to the other? ...

As explained in the editing help, in MarkDown you can achieve preformatted text by using four spaces indentation. To achieve this after typing (or copy pasting) the code, simply select the relevant part and the click on the code button in the editor (between blockquote and insert image) or press Ctrl+K. To test this I have taken an example of for cycle in ...

You can also introduce new commands only when they are first needed. Such as $\newcommand{\where}{\text{here}}\where$ or $\where$. Source: You can also introduce newcommands only when they are first needed. Such as $\newcommand{\where}{\text{here}}\where$ or $\where$.

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 @...

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 ...

Granted this is a temporary reason, but I and I suspect many other members use smart phones with old browsers, where such rendering takes time. This is tolerable for questions, less so for the front page. Also, question titles without symbols are more friendly to web search indexing, so lots of people outside MO can find and have a better chance of ...

Once typographers are allowed to run amok, there is no way back to normality. For it'd be only a question of time for multi-coloured flashing parts of text, and what not, to start to appear. Contributions to MO are akin to papers in a journal or chapters in a book, where the editors are free to impose a uniform typography style. Are there any Markdown MO ...

I suppose that all of us who don't have English as mother tongue would rather not have the idea of capitalizing nouns or other "key words" in titles. At least to me that idea has never occurred for a question in MO (even though it is the general rule for nouns in German, my mother tongue! - which is in my opinion somewhat obsolete). It is about questions, ...

Before the migration to Math.SE last year, the front page of MathOverflow did not render math mode formulas. This may be a leftover habit. Here's an old discussion: http://mathoverflow.tqft.net/discussion/1040/latex-in-titles/

There are several things that should be said about your question. It is, in my opinion, a bad practice to use MathJax for formatting and not for Mathematics. So it is not good to use MathJax to achieve strikethrough. (MathJax also gives information which part is mathematical formula and which part is text. This information is used, for example, by screen ...

Here I typed some code, then selected it, then clicked on the {} icon (preformatted text), and the result looks like this: for(int m=0; m < N; m++): <<&etc.>>

$ %% Preamble %% \newcommand{\test}{\text{test}} $Here it starts in the way it should start. It is a little easier to parse than the variant proposed by quid.
