Does anyone else think that his publishing contract is odd? He mentions it being a 50% revenue split after publishing expenses, I was under the impression that any contract that put any of the costs onto the author were considered bad to the point of exploitative[1][2].

It obviously couldn't have worked out terribly for him if he was making $3 a sale but I wonder if this is more common than I thought.
