Manning once offered me the co-authorship of Hello Python for 5% royalties and (unspecified, possibly 0) advance. To collaborate with an Australian co-author in an Australian timezone. I declined. Figured if I wanted to write a Python book I could do it for sole authorship, at time and pace most convenient to me, for 100% ownership, 80-95% royalty, most format freedom, etc. with the biggest loss being less marketing power. To this day, not sure if I made the right choice or wrong choice. But declining appeared right at the time.
