All my life I knew that there were two genders; male and female, apparently however I was totally wrong and ignorant.
According to digg.com there are 16 types of genders that you have to choose from when creating your profile.
6- Bird (Birdy Egg from Nest Ville – Oak land, signing up to Digg)
16- None of the above (Aliens who want to Digg)
See how ignorant I was =)
