What percentage of the book revenue do you plan to share with contributors?
What author royalties there are will go towards getting print versions of the book to our largest contributors, and then to Ryan and I as editors.
I don't think it would be feasible to split the royalties fairly amongst all our contributors; not only would it be a large overhead, but the actual amounts would be pretty tiny unless you've written a pretty large proportion of the book. And if you do that, we'd be happy to talk to you about sharing some of the royalties.
What proportion of the book do you expect the editors to write?
On the other hand, should contributions be extremely low, we are still on the hook with O'Reilly to deliver all of the book.
