"Is it true facebook can track user browsers even after they are logged out of facebook?" Zuck: "I need to get back to you on that"
Honestly is there anyway that he could explain the Facebook Pixel/ad network that wouldn't just be describing any ad network? By definition, ad tracking (cookies etc...) is opaque to most people and explaining it publicly would make it seem like FB is doing something more nefarious than others.

The only ad network in front of Congress today, was Facebook. 'Everyone else is doing it' or 'this is the nature of the business' doesn't qualify as an excuse. Perhaps it could have been good for the large public to know what goes on with ad networks these days.
