I looked at my traffic sources and saw that I got traffic from another hubber. How does that happen?

Simple, hubbers read your hubs. Traffic is from hub pages.

They must have linked to your page. Perhaps they wrote a relevant hub and thought to link to you, or really liked it :-).

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.
