I've tried to host an instance of MathJax on my server before, but that means installing a bunch of bloat like Node.js on the server end. Plus, I'm not even sure it'll improve response times by that much. Image based solutions look absolutely horrible. Is there any clean solution to writing pretty equations in HTML? If anybody knows of one, please let a poor and struggling mathematician know.
Edit: An additional grievance:
\underbrace will break MathJax. It doesn't even compile the rest of your document if you have one of these bad boys in your code! Someone please save me.
