Do I need to unpublish then republish to have new content sent to my fans and into feed?

No, you don't need to unpublish then republish to have new content sent to your fans and into feed. Copy the hub into a new hub with a different title. That would work.

But you'll never need to do that if you link your hubs together. That way, your fans will eventually come across what you want them to see.

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.
