Q:

Option to *not* display age in profile should be available

As part of privacy options, users should be allowed to control whether their age is displayed (or even has to be entered!). We don't want to potentially help age discrimination from potential employers.  Most sites in today's networked world allow one of the following "privacy" settings:

No requirement to have full birthday or age entered
If age >= 18 attestation is needed for site legal reasons, allow user to prohibit the birthdate and age from appearing in a profile
Allow birth day (month day only) to be public

A:

You can delete your birthday and age setting and the age will disappear from your public profiles. The birthday’s placeholder text even mentions that it’s “only used for displaying age”.
I’ve seen enough profiles without a displayed age, that it’s definitely not a required field or something you can't change any time you wish.
