Loosely related to your toot; similar story but positive
@chr one of my coworkers didn't realize singular they existed - and defaulted to writing "she", because he saw the problems with using "he" only and didn't know of a better solution. Iirc he was talking about software developers as well in that text.
Also, when I told him about singular they, he enthusiastically asked me how to use it and changed the text immediately.
We need more ppl like him.
