I lump usernames in with proper names. I guess if you don't lump them together, it's not precisely the situation. But I still feel like I can use that article as validation for not wanting to use 'they' in certain situations. e.g. (if I didn't know your gender, like I don't know most genders on HN), I'd much prefer "tptacek said that ve likes bcrypt" over "tptacek said that they like bcrypt".
