I haven't got a terrific amount of Hubs, but I am still noticing surges and plunges. - Nice when it surges, and dispiriting when it plunges - Damned if I know what causes them though!
I haven't cashed out any significant monies either. I had 1 article to go viral and earn $40 in two days once.(not on Hubpages) It stopped as quickly as it started. When you get tons of comments, you will know.
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.
