Loves this last paragraph especially: "Unfortunately, that's too rare a commodity. A lot of people in our industry haven't had very diverse experiences. So they don't have enough dots to connect, and they end up with very linear solutions without a broad perspective on the problem. The broader one's understanding of the human experience, the better design we will have."
Big point to take away from that is you can't make great consumer products unless you have a good understanding of people and human nature.
Guys like Markus Frind, Jonah Peretti, and esp Zuckerberg are great examples of good hackers who also have that rare quality of knowing what makes people tick.
No surprise that broad thinkers are able to connect the dots better. Makes me think of awesome writers in HN like PG and Derek Sivers who continually write quality posts and insights.
