When you make a Hub, there is a box on the right that says "Related Hubs" and lists similar hubs?

Yes, related hubs are picked from hot/best hubs from that related category and some of them are related to the tags you've added to your hub.

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.
