Google+ is introducing "infinite" ways to define gender, letting users describe themselves using whichever terms they feel comfortable with rather than relying on the ternary "Male," "Female," or "Other" system.
"Now the gender field on your profile will contain four entries, 'Male,' 'Female,' 'Decline to state,' and 'Custom,'" writes Google software engineer Rachel Bennett. "When 'Custom' is selected, a freeform text field and a pronoun field will appear. You can still limit who can see your gender, just like you can now."
