You answered it yourself...your blog is swimming in ads....it shouldnt be about how many ads are on your blog...but the quality of it...i havent seen it so I cant judge but I heard that people have more of a chance of making decent income if they have more than one site or blog affliated with one or more programs. I am trying to figure it all out myself. But the key to it all is quality and driving traffic to your site/ blog.Goodluck.
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.
