I'm afraid I don't understand what rubric you're talking of. Are you asking me whether employers across the world should read HN? Or is that an autocorrect typo for "rule"?
If the latter, yes, certainly. My last two employers had to hire US and Canadian developers anyway just to be able to sell to the US/Canada, so I guess it's already the case.
Consider purchasing a better English dictionary. I worked in the ESL/EFL industry for years and never encountered the word rubric as a synonym for category/chapter. It is commonly used to refer to a guideline or rule.
