It's noticeably more of a joke than using tabs vs spaces vs null bytes for indentation. That has some legitimate arguments in a few directions, even if there is only one reasonable choice: null bytes assure everyone that you're not secretly writing C code, and they have no visual representation so you're free to display the code any way you like. Not everyone gets that it's a joke of course, but they're probably government bird operators and you are free to just nod and quietly back away.
