By far the dumbest questions through the entire meeting, though:
Sasse: "Do you hire consultants to tell you how to tap into dopamine feedback loops to keep people addicted?"
and (this one had me rolling) Senator Deb Fischer: "How many categories of data do you collect for all 2bn users?"
Zuckerberg: [acts confused]
That said, perhaps Zuckerberg's vague and generic answers could have been a result of ill preparation on -his- side, too. The CEO, while the head of a company is only involved so much in the day-to-day issues and goings-on. As the spokesperson, he didn't do much by way of transparency or work to improve FB's reputation today. Maybe some technical staff should additionally be interviewed. A list of potential topics prepared by staffers, to be discussed at the hearing would help Zuckerberg in figuring out what information he should know.
