I honestly don't know how anyone could make a living by writing books these days? Besides the obvious; like publishers don't pay like they used too, your book will be traded on p2p?

I don't know, but am always saddened by what Americans do read. I didn't read the article, but stay away from vanity press(Bertram Capital--Author's solutions).
