Square’s mobile app Cash lets you do one thing: send money to a friend. “I think I’m just an editor, and I think every CEO is an editor,” wrote Jack Dorsey, Square’s CEO. “We have all these inputs, we have all these places that we could go…but we need to present one cohesive story to the world.” In organizations like Square, you’ll find product leaders saying no much more than they say yes. Rather than chase the market with follow-on features, they lead the market with a constrained focus.

My take: CEO or not, we are all editors.
