I really like the point that is made about co-founders being ying-yang of each other. Hacker-hacker co-founder duos are destined to fail in the same way husler-husler startups are. Bridging the gap between husler and hacker is difficult though. Far too many hackers are hesitant to hire a husler, and far too many hustlers are hesitant to hire a hacker. Actually, I don't think 'hesitant to hire' is the right phrase... maybe 'unable to recognize'

Great quote: "Going to a networking event to find a co-founder is like going to a party to find a wife" (I think this is by David Tenner, a UK entrepreneur). The co-founder is your other half and you don't become ying and yang instantly on a first date unless you are very lucky!
