figured out you can change your sex on plurk with not even a single letter to the admins.
It's not really an issue for me since I'm not in the middle, though I ~do~ have a penis.
Finding dates over the internet would be difficult without specifying a gender.
Plurk is aimed at young people, I think. They like to put tab A into slot B as much as possible, I think.
