Google Plus lets you define your own gender

Facebook gave its gender non-conforming users a better way to express themselves early in the year, and now it's Google's turn. An update to Google+ rolling out over the next few days will let you type in a custom gender for your social networking profile instead of having to settle for "other" -- you won't have to constantly explain yourself just because you don't fit into the male/female binary. You can also choose a pronoun, and it's still possible to limit who sees your gender. This is a small tweak to the code, but it should make a big difference if you haven't been comfortable with your G+ identity so far.
