Yes and no. The comments themselves do not attract more visitors. But if someone that has 600 followers comments on your hub, then all 600 of them notice that, that person has commented.So each one of them can read your hub as well.. So it can benefit you to have lots of comments on your hubs, but the comments themself do not mean more people will come to your hub.
Yeah that's right i'm agree with Johnrr631992 :).
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.
