Also, engineering is not solely about output. In fact, for something as big and established as Twitter, output is probably secondary to availability. Good managers ensure their teams have "slack." Because if something is on fire, or a pressing deadline appears, etc..you need to not be at 100% to absorb that. People disrespect maintenance work & being available. Even here on HN.
