I have one to add:

Programmers believe languages have a flag.

I used to work on a system that supported multiple languages and had to fight very hard not to put a country’s flag next to each language on the front end. People’s responses to the “wrong” flag being used for their language ranged from slightly annoyed to extremely volatile…

I saw the one that started it all about names not long ago. This should be a suitably anxiety-inducing read of all the edge cases I had never considered. I’m not sure if I should laugh or cry… 😭
