Bernardo Huberman and Christina Aperjis:

Why not pay individuals for their data?

Kate Murphy:

You know that dream where you suddenly realize you're stark naked? You're living it whenever you open your browser.

Cyrus Rangan, director of the toxicology bureau for the county public health department and a medical toxicology consultant for Children's Hospital Los Angeles:

All it takes is just a few swallows and you have a drunk teenager. There is no question that it is dangerous.

Jeff Hammerbacher:

The best minds of my generation are thinking about how to make people click ads.

Tom Simonite:

Even as Facebook has embedded itself into modern life, it hasn't done that much with what it knows about us. Its stash of data looms like an oversize shadow. Everyone has a feeling that this resource will yield something big, but nobody knows quite what.

John Gruber:

Yahoo had a chance to buy Google in 2001 but then-CEO Terry Semel didn't pull the trigger. I don't think Instagram is the next Google, but Zuckerberg sure as shit doesn't want Facebook to be the next Yahoo.

Henry Blodget:

When talking about Zuckerberg's most valuable personality trait, a colleague jokingly invokes the famous Stanford marshmallow tests, in which researchers found a correlation between a young child's ability to delay gratification -- devour one treat right away, or wait and be rewarded with two -- with high achievement later in life. If Zuckerberg had been one of the Stanford scientists' subjects, the colleague jokes, Facebook would never have been created: He'd still be sitting in a room somewhere, not eating marshmallows.
