Notable pull quote: "It's important to note that if any other company spent until their EPS was negative, investors would /flip/. Amazon is playing with razor thin margins while trying to scale up a platform to end all platforms that we might someday use for everything without thinking about it."

So again, like Apple and Facebook, everyone knows the CEO is playing the long game and doesn't give a crap what the stock price is.
