Having said that, I actually think in reality this conversation is very difficult to have.
If you've never started a start-up before you just don't know what to expect so some of these questions don't make sense. I would have WANTED to answer these honestly, but when I started HireArt I really had no clue whether I'd want to raise outside money (let's just get started was my motto) or which attributes we'd en up clashing on.
I think this makes more sense if you've started a company before and can anticipate the feelings and issues that will arise (but in that case you probably already know which questions to ask and don't need a guide).
Overall I guess I think it's really important to talk and to talk a lot. However, don't estimate how much there is that you just don't know about yourself until you're doing the start-up.
