I don't mind monospace too much, but definitely not the font chosen... the spacing is just awkward to say the least, my eyes just want to wander when trying to read... and I look at monospace fonts in a code editor all day. Fira Code or Inconsolata.

That said, I'd probably just stick to "sans-serif" and let the browser/os preference hold. It's likely a helvetica/arial alike anyway and can be set by user preference if really wanted.
