Mine is doing the same.. it was at 84. Now its at 78. I think it might have to do with the amount of traffic I have on my Hubs.
Also I think there might be a correlation with the fact that I have added links in my hubs to website's and I think HubPages may frown on linking out externally.. But I am new as well and trying to figure this out.
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.
