The main Q&A on this (here's one, and another one, and of course this one all seem to be 3+ years old. I'd accept that this question is a duplicate of this question which seems to have comprehensively covered all the bases last year.
I'm not asking why we don't have it. That seems to have been covered a lot. I am asking are we at the stage where we can at least start talking about it? Here are a few examples of posts that would benefit from MathJax (hurriedly hashed together so they may not be the best) are (and feel free to add your examples to this list):
- Answer to: Determine if two rectangles overlap each other?
- Question: Gram Schmidt with R
- Question: Speeding up Julia's poorly written R examples
- Question: Ukkonen's suffix tree algorithm in plain English?
- Question: How to pair socks from a pile efficiently?
- Answer to: Plot a heart in R
- Answer to: Cannot rotate from one specific orientation to another
- Answer to: Creating a rotation matrix based on two vectors
Surely WebKit and native rendering of MathML have come a long way since 2009 and we might be at the stage where it is feasible to at least start discussing the inclusion of math markup on Stack Overflow? Are those really heavy dependencies still necessary? Is it still better to carry on uploading images where necessary? Every time this has been bought up, it's been a blanket NO.
One of the reasons frequently trotted out is that you shouldn't need math markup on a programming site or it's not often needed. Without any support for math markup how can you guage how much interest there is in using it to help illustrate questions or answers?
I'd love this post not to get closed and to generate some fresh debate given advances in native rendering of math markup in browsers.
