Said Sarah Ban Breathnach, "Dream, do, detach." Google lost about $13 billion worth of value on Thursday evening. Why? -- you ask. Wasn't their income up by 28% over the past year? Yup. Isn't that pretty impressive? I mean, I'd like to see my income increase by nearly 30% in just one year. It is impressive. But....everyone expected Google's income to go up by 29%. What? People dumped Google because its income was 1% shy of expectations? Yup.
