Facebook cares about your identity.
There are many different interpretations of that statement, but this time it's (mostly) good; the social media giant now allows users to identify as genders other than male and female. Options include 'transgender,' 'intersex,' and 'fluid,' with appropriate pronouns. Facebook worked with LGBTQ organizations to come up with the changes, which they hope will help users be their "authentic" selves.
Users who make the change should study Facebook's privacy settings first, however, and watch out for even more tailored advertising.
