The mainstream press was not aggressive enough after 9/11, was not aggressive enough in asking questions about a decision to go to war in Iraq, was not aggresive enough in asking the hard questions about the War on Terror. I accept that for the Los Angeles Times and the New York Times.

The fact that Edward Snowden didn't approach the New York Times hurt a lot. It meant two things. Morally, it meant that somebody with a big story to tell didn't think we were the place to go, and that's painful. And then it also meant that we got beaten on what was arguably the biggest national security story in many, many years. Not only beaten by the Guardian, because he went to the Guardian, but beaten by the Post, because he went to a writer from the Post. We tried to catch up and did some really good stories that I feel good about. But it was really, really, really painful.

The New York Times is and has always been a digital leader. The report only cited some areas where we fell down.

I know this is going to get me in trouble, but I'll say it: The whole notion that I am supposed to constantly tweet is ridiculous. There are a lot of journalists at the New York Times who tweet. I am not opposed to it. But I don't have enough time. And editors don't have much to say. My world consists of this office, this floor, my apartment and wonderful conversations with our reporters and correspondents - all of them know a lot more about the world than I do.

It used to be, if you were a reporter, you wrote a story and then you moved on to the next one. We were used to people coming to the New York Times. We waited for them to turn on our website or to pick up our print paper and see what we have. We now understand that we have to make our stories available to our readers. A lot of people get their news from Facebook or Twitter and we want to make sure that they see some of our best stories there, too. We do this more aggressively now than we did before.

I also don't think all of the revenue will come from digital subscriptions. We have in the New York Times a mix of revenue sources and it will continue to be a mix for quite a while. What makes me more nervous is that we built this newsroom on a really high profit margin that has eroded significantly over the last years. I'm nervous that we won't continue to have the profit margins that allow us to have a big, robust newsroom.

I grew up in the traditional American newspaper world with a morning paper and an afternoon paper competing with each other beat by beat by beat. It was the most fun I've ever had. And it was great for journalism.
