Grant Facebook COO Sheryl Sandberg this much credit — she's endlessly creative in her explanations. Take her reasoning for opening up an international headquarters in Dublin, Ireland : "The talent pool in Dublin is world-class and recruiting local talent will help us better understand the needs of local users and the regional dynamics that, in turn, can give us better insight into what features matter most.” What she really means: It's a cheap place to hire a lot of drones in customer support. And Ireland's tax rates are rock-bottom low . If Facebook ever makes money, it'll be set. Kudos to Sandberg for dressing up a cost-savings maneuver as a way to advance international understanding.
