Facebook’s letter documents its core values: focus on impact, move fast, be bold, be open, and build social value. And as I read those bullets, I see two people at the table defining them. A high impact, fast moving and bold Barbarian who couldn’t care less about the Biz Dev guy who is arguing for being open and building social value.

Both people are essential to a business thriving, but only one of them knows that hacking is important.
