Those are all great questions, but I wouldn't necessarily expect to see all of them on a cofounder finding site. I'd rather ask these questions in person. I'm looking for people who can build stuff, so a meetup of programmers looking for co-founders would be more useful.
Besides, my comment was directed at you personally in terms of working with me, not as a general comment on co-founder finding sites. Sorry, I assumed you were looking for a co-founder, but maybe you're not?
