This is not an easy question to answer definitively but the general idea about the Google Panda is that all sites with low(er) quality content will be hit, so yes, all will take a hit but some will suffer more than others.
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.
