As long as you are using your own original content, you can write a hub about anything. Inspiration comes from many sources on many levels. I would make sure it was something complementary to the hub, rather than something on the same line as the hub in order to draw more readers.
Hope this helps! Good luck!
Yes, you can write a hub about the comment you posted on someone's hub. It can be the foundation of the article, but you will have to elaborate greatly, give more detail, so as to have enough content.
Of course you can. You can make a hub about virtually anything. It doesn't matter where you get the idea for a 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.
