I don't speak from experience but there is social network software out there that you can use to start a social network. Some of it is open source software and other software is for sale. It's up to you.
Google it. I'm getting ready to start a site, though it might still be a few months away. I googled how to do it and there is lots of free information to show you how step by step.
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.
