Should I care about culture, when my app will not emigrate?

Even if you're app is only used in the US, there's always a chance, if you're targeting a large audience, that a user could customize their regional settings or have their system setup using a different region.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
