I am sorry I have not answered this question! I had no idea that there were any questions anywhere on the site for me and I am honored that you asked me something, lol.
Zero, is the answer to your question. I do not write for money, though it would be nice. I was thinking about this today as I walked, ironically enough. I suppose I could focus on one category and write towards becoming an expert. But those hubs would not be as personally satisfying as the ones that I write from my heart. And the ones I write from my heart are not money makers.
So, the answer is zero!
Hope you are having a good experience here.
