content: some people were wasting time making salary spreadsheets rather than do their job  Google is not a company that cares about people wasting time on stupid shit that only serves to stimulate their mind. They encourage it. They give their people one day a week to do whatever they want. They have people working on cars that drive themselves -- that is sounding more reasonable now but 5+ years ago when they started it, it sounded absurd. And they did it because that's Google.
