Zuckerberg says that Facebook shouldn't get all the credit, that internet.org is a "big coalition across the industry."
...though having the most-used app gives them "some position" he indicates.
"There's just no way that Facebook can do this by ourselves. If we come away that this is in some way my vision or something that we're doing that would be completely wrong."
Kirkpatrick is now asking about the Snowden revelations. "Could this potentially be a problem for the success of Facebook in the future overseas?"
Zuckerberg: "The NSA issues I think are real issues for American internet companies. Trust is so important."
He's glad that they now have the permission to share the requests that they get, and that the volume, thousands and not millions, is important.
He says the NSA was "way over the line" in terms of not being transparent enough.
"They're only now starting to get to the range of where they should have been and this thing could have all been avoidable."
First question: "What is the role of literacy in this?"
They're taking a series of questions and Mark will then give answers after that.
So, sit tight for a moment.
Okay, we're taking all the questions first... and then he's going to answer them later.
Okay, first question, about the government role of carriers.
Zuckerberg is saying that this isn't anything for one company or government to really manage.
"There are going to be a number of things pretty soon that show pretty good partnerships that are public/private partnerships."
Next question: will the attitude toward WhatsApp data consumption change?
Zuckerberg: "WhatsApp is going to continue to operate completely autonomously."
But, they'll have access to Facebook services, but "the vision is to keep WhatsApp services exactly the same."
People are leaving the keynote in droves now. I think this is actually an interesting part of the discussion!
He's saying that everything WhatsApp sends, photos and text, is not stored by the company. It's deleted "almost instantly."
And, now the literacy question.
He's talking about "universal forms of communication" including simple photos that are easy to share.
... we're gathering more questions, sit tight.
"China's a little challenging for us because we're not running there..." but he believes that Chinese companies can do the same.
Will there be another Snapchat acquisition? "After buying a company for 16 billion dollars, you're probably done for a little while."
And that's all! Big applause for Zuckerberg and people are running for the doors.
We're going to get out of here too. Thanks as ever for joining us!
