RE: the CTO title. It's easy to be the 'chief' code monkey, when you're the only code monkey. =)
I agree with your sentiments about working hard to fix the problems. I have been heads down on this project for 2 years. The psychological strain from the 12 hour days, 6 days a week is really wearing on me. I'd like to have a personal life, too please.
No, I'm not looking for other work. I've told my partners that I'm in it until there is no more 'it'. If I were looking for other work, it wouldn't necessarily have to have some high-and-mighty title like 'CTO', though.
