I'm not stating it is not nice, or helpful to have some of the information, I'm just saying it is up to the individual what info they want to share... They should not be required or feel it is mandatory or feel pressured to provide it. Just my opinion... I'm not a bad guy, I just am sort of private and I respect other that are also. It is not a bad thing, nor a good thing, it is just a thing...
I often look at a persons profile to see what info they provide, just curious of location, often I like to know and use a persons real first name, and age, but if they don't provide it,,,, no biggie.
