It all depends on the topics you write about, how well you write, what time of day you post, what day you post and how well you promote your hubs. It's up and down really, like all things. You seem to be pumping out a TON of hubs, nonstop... Some will appeal to people, some won't, but your followers might only comment or view your hub if they're very interested since you write so often.
Luv your questions and wrote two hubs to answer these for you. Please read these. hubpages.com/hub/getmoretraffictoyourhub....
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.
