I wish more sites would follow those principles. One of the reasons I made the switch[0] was because people from countries with limited internet access wanted to use things I was posting as a reference. Unfortunately I don't have a good replacement for MathJax right now. A side effect is that everything displays nicely even on a phone, with no work. I am aware that my website is ugly but I'd rather have one that is readable.
