I would not bother trying to interpret it at all, it happens all the time and I know that next time I sign in it will probably have changed yet again!
Just interpret it as a normal fluctuation. All you can do is be the best little hubber you can and give what you hope is good advice to others and hope that it works out. I wouldn't worry about it.
Watch how a butterfly flies. But seriously, only Hub Management knows. FWIW, IMO, posting questions and answers (this section) probably doesn't do much for you -- except as it may help to increase your traffic by people seeing your comments or questions, then going to your profile, then maybe to your Hubs from there.
Probably more better is posting comments on others' Hubs. But, the "biggie" is Hubs that have Hub titles and subjects (keywords) that Google searchers are looking for so you get traffic from outside of HubPages. (That will also get you some more AdSense money.)I have never participated in the forums, so I have no idea how much that helps, if at all.
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.
