As the title says, I could use an exhaustive list of all Stack Exchange sites that use MathJax. If the list included any site-specific customizations made to the MathJax configuration on each site, that would be even better.

    I wish all. – John Militer Jun 18 '17 at 20:33
  • @JohnMiliter I remember some time a guy at some post informed me that Stackoverflow doesn't support this, because it's an overhead. However, that's just some guy in the internet, like me! :) – gsamaras Nov 9 '18 at 8:32

Why doesn't [site X] support MathJax?

MathJax increases page load times drastically, so it's only supported on sites that have demonstrated a serious need for it. For more information, see LaTeX on Stack Overflow?

    Just as a remark: It is intentionally deactivated on TeX.SE, cf. Can we turn off math-tex please?, and to clear up a common misunderstanding: It is also off-topic there to ask MathJax related questions. – Speravir Jan 18 '14 at 5:10

    @Speravir: apparently, the topicality of MathJax questions on TeX.SE is "marginal". – Ilmari Karonen Jan 19 '14 at 20:14

    Please enable it on Stack Overflow. – endolith Aug 25 '17 at 3:06
  • Physics SE doesn't have MathJax on the meta site, which causes continuous troubles there. – peterh Sep 20 '17 at 13:50
  • @endolith The SE has a strong urge to make all page rendering in tenths of seconds possible on most client machines. I already tried to convince an SE insider from that the mathjax should be conditionally initialized on the page requests where there is a formula on the page. The answer was a polite mentioning, that they want to remain still so fast (then became unresponsive + nothing happened). – peterh Sep 20 '17 at 13:56
  • @endolith It can also explain, why the SE handles the SO differently. For example, on the SE sites, it is no problem, if there is some topic overlap. But it seems, they have a strong wish to collect practically all programming questions to the SO and that it should remain undivided and very fast, forever. This is likely also the reason, why the SO has a lot of improvements what the SE sites get only with a delay, or never. Maybe business logic could be the most realistic explanation (i.e. bosses simply calculate paid work hours / generated income and these numbers can be strongly for the SO). – peterh Sep 20 '17 at 14:01
  • @endolith Btw, there are simple userscripts which enable mathjax simply everywhere. – peterh Sep 20 '17 at 14:03

    The "funny" thing is, that tex.stackexchange.com somehow doesn't have MathJax support, on mysterious reasons. – peterh Aug 22 '18 at 23:23

    @peterh The reason why is explained here: tex.meta.stackexchange.com/questions/1272/… – Sonic the Wizard Werehog Aug 23 '18 at 5:40
  • @SonictheInclusiveHedgehog That is not an explanation, just a simple statement. The very little "explanation" part is non-sense (code can be still shown, just \$s it should be enclosed in `). Probably their real reason is that having MathJax support would focus the site to MathJax and distract other Tex implementations. However, if it is so, then they should say that. – peterh Aug 23 '18 at 6:16

    @peterh If you disagree with their decision to not support MathJax, the best place to contest that would be on their per-site meta, not in comments here. – Sonic the Wizard Werehog Aug 23 '18 at 6:46
  • @SonictheInclusiveHedgehog I don't want to contest it, in all others they are nice people. – peterh Aug 23 '18 at 6:47
