Back in my day, I was taught to use masculine pronouns.
The user chooses a password, and then he types it in the text box.
I'm fine with that. but a male coworker insists on using he/she, which I find needlessly distracting and complicated.
I hate using they and their. I find that too convoluted, and not nearly clear enough when you want to talk about one person doing one thing.
I like "you" but you can't always get away with that. Sometimes you're telling someone about what his users can do.
Interspersing "he" for some things with "she" for others is also distracting, but maybe the closest thing to "fair" that I can come up with.
What is the current thought on this? What's the most acceptable way to go?
(Frankly, I wish I could get away with "it." As in "it puts the lotion on its skin." Creepy, right?)
