On the old site, you could enter whatever you wanted into the date of birth field, as long as you were at least 13 years of age. Now, we can also *hide* our age. Due to the (historical) nature of this site, being that it was a community geared towards teens and young adults, it made sense to display ages. Users would regularly come into contact with people with huge age differences. The question is, should it be mandatory to display your age?
