I went and coded a verbosifier, so it’s possible to write <msup>a 2</msup> + <msup>b 2</msup> = <msup>c 2</msup> and not <msup><mi>a</mi><mn>2</mn></msup><mo>+</mo>...: https://github.com/jeffkaufman/mathml_verbosifier
It turns out Feedly (and maybe other RSS readers?) strip out MathML, so even if they’re using a rendering engine that supports it you see nothing. So I’ll stick to ascii math for a while longer.
Two updates:
