This is what I do. I have a spreadsheet that tracks followers, views, (it used to show reads/fans), total earnings and subscribers. On a separate sheet, I track the earnings, by month, of my current stories.

I think part of the earnings issue is time. Some of our readers are spending more time writing now that it pays off. I'm not sure where to dig out more time, but am trying. LOL Remember that prompt that asked what you'd do with an extra hour? LOLOL

I also wonder if the Medium Powers saw the $$$ going out and dialed back the amount paid per whatever their payout stat is.
