How can I get these \nabla s to render, is there a plugin or something ?

HN doesn't support LaTeX in comments sadly, so I am just writing it out as you would before rendering it with LaTeX.

Maybe there are add-ons that detect valid LaTeX math symbols and convert them whenever possible but as-is you can't get it to render within the comments.

Yeah, it’s a brain-render unfortunately. Once you’ve written enough latex you work pretty comfortably with just the text for communication.
