Just the day before, President Barack Obama had signed on and begun sending out photos. This seemed like a real sign that Instagram had arrived. Obama already has accounts on Flickr and Facebook. He (or his people) must have seen something unique and wonderful in Instagram's audience, some way to reach people via that channel that it couldn't through others. When the President joins your network, it's news. And while it's great news, it can be the kind of thing a company isn't prepared for. But as it turns out, Obama is a fractional compared to Justin Bieber.

"Unfortunately, death is a fact of life. I don't think it's happened to me any more unfairly than to anyone else. It could always be worse. I've lost a lot of people, but I haven't lost everybody. I didn't lose my parents or my family. But it's been an incredible education, facing death, facing it the way that I've had to face it at this early age."

An interview with the former president about the upcoming election and American consensus.

But now, being a celebrity yourself, you feel differently? I've subsequently changed my opinion. Brad Pitt doesn't have a superpower at his back. He just has some crazed fans and paparazzi. But now, having had all three, I must say, I'm not terribly impressed with the experience.

After a Chinese immigrant couple were charged in their daughter’s death, supporters say they’re vulnerable targets of the American justice system.

A conversation with the comedian.

JW: You’ve talked about how you’ve had to explain moral lessons to your daughters, but do it in an inarticulate, catchy way. It’s almost as though you’re writing material for them. What’s the place of morality and ethics in your comedy? I think those are questions people live with all the time, and I think there’s a lazy not answering of them now, everyone sheepishly goes, “Oh, I’m just not doing it, I’m not doing the right thing.” There are people that really live by doing the right thing, but I don’t know what that is, I’m really curious about that. I’m really curious about what people think they’re doing when they’re doing something evil, casually.

The main thing that attracts me to Buddhism is probably what attracts every artist to being an artist—that it’s a godlike thing. You are the ultimate authority. There is no other ultimate authority. Now, for some artists that’s difficult, because they want to have the art police. They want to have the critic who hands out tickets and says, “That’s too loose.”

A memory of interviewing the late great songwriter Townes Van Zandt shortly before his death.

"Of course, sexuality has never only been about reproduction, obviously, with human beings, anyway. But at the moment it's almost cut free to kind of float wherever it will float. And sexuality has been mixed with many things that I think the ancients would have been surprised to find it mixed with."

Breaking the news of the Kennedy assassination, an oral history:

Wicker: [In the press room] we received an account from Julian Reed, a staff assistant, of Mrs. John Connally’s recollection of the shooting…. The doctors had hardly left before Hawks came in and told us Mr. Johnson would be sworn in immediately at the airport. We dashed for the press buses, still parked outside. Many a campaign had taught me something about press buses and I ran a little harder, got there first, and went to the wide rear seat. That is the best place on a bus to open up a typewriter and get some work done.

GROSS: Let me stop there. You're talking about cutting yourself ... HAMMOND: Yeah. GROSS: ..with a razor. HAMMOND: Mm-hmm. GROSS: So I interrupted you. You're saying it does what? HAMMOND: Well, it creates a smaller, more manageable crisis than the one that has you gripping the carpet.

A conversation with the 88-year-old abstract painter.

PALTROW: Did you design camouflage while in the army?

KELLY: I did posters. I was in what they called the camouflage secret army. This was in 1943. The people at Fort Meade got the idea to make rubber dummies of tanks, which we inflated on the spot and waited for Germans to see through their night photography or spies. We were in Normandy, for example, pretending to be a big, strong armored division which, in fact, was still in England. That way, even though the tanks were only inflated, the Germans would think there were a lot of them there, a lot of guns, a whole big infantry. We just blew them up and put them in a field.

A Q&A:

My mother was called to school frequently because I was yelling out things in class, quips in class, and because I would hand in compositions that they thought were in poor taste, or too sexual. Many, many times she was called to school.

An interview with the author.

"We live in a frightened time and people self-censor all the time and are afraid of going into some subjects because they are worried about violent reactions. That is one of the great damaging aspects of what has happened in the last 20 years. Someone asked me if I was afraid to write my memoirs. I told him: 'We have to stop drawing up accounts of fear! We live in a society in which people are allowed to tell their story, and that is what I do.' I am a writer. I write books."

GQ: Your relationship with your biological father seems complicated. Lil Wayne: He don't give a shit about me. And I don't give a shit about him. I know his friends be like, "Damn, nigga. That is not your son. Stop lying. Nigga, you could be living in a motherfucking ranch right now, nigga." You know, whatever your father's into, if you're rich, you're gonna get him that shit. I would've got that nigga all kinda harnesses, ranches—you know what I mean? I saw the nigga recently—I had a show in New Orleans. And I ain't afraid to put this out there, 'cause this is just how much I don't give a fuck about a nigga, and I want people to see how you're not supposed to be. I was parked at the hotel, and I saw him walking outside the hotel. Just walking back and forth. I'm like, "Look at this nigga! You gotta be looking for me." If Lil Wayne got a show in New Orleans, the whole of New Orleans knows. Basically, you're not there for nothing else but me. So I call my man on the bus. I'm like, "Nigga, that's my daddy." He's like, "Word? Oh shit. That nigga looks just like you!" So I tell my man, "Go see what's up." So my man goes to holla at him. He tells my man, "Oh. I didn't know y'all was here. I'm here waiting for this little ho to get o¬ff. Get off¬ work from the hotel." For real? That's when I was like, "Typical Dwayne Carter." So that's what's up with me and my real father. I don't want to look like his ass, but I do.

Jonathan Safran Foer It’s been an awfully long time since we last spoke. Four years? And it’s been a long time since the reading world last got new material from you. About seven years? What’s been going on? Jeffrey Eugenides I’ve been writing a book.

Recently discharged, an undocumented immigrant discusses his treatment.

In a city with a large immigrant population, it is not rare for hospitals to have one or more patients who, for reasons unrelated to their medical condition, do not seem to leave. At Downtown, where a bed costs the hospital more than $2,000 a day, there are currently three long-term patients who no longer need acute care but cannot be discharged because they have nowhere to go. The hospital pays nearly all costs for these patients’ treatment. One man left recently after a stay of more than five years.

N.K.: So when you saw the photo of Neda Soltan, what did you think? M.A.: It was incredibly sad, due to many reasons. First we have proof that that scene was staged, and she was killed later, at a later point. This footage was shown for the first time by BBC. Our security officers and officials had no information of such a thing. but if BBC makes the complete footage from beginning to end available to us, we will analyze it, we will research it because we do search for those who are truly guilty of murdering this young lady. And also, a scene fairly close to this—almost a photocopy I would say—was repeated previously in a South American country—in a Latin American country. this is not a new scene. And they previously tell those who are due to participate, they tell them that “you will be participating in making a short footage, a short movie, a short clip.” After their participation is finished they take them to some place and they kill them. If BBC is willing to broadcast this film, this footage in its entirety, any viewer would be able to distinguish whether it is as we say or it is as they maintain.

An interview with Rudy Giuliani’s fresh-out-of-college head speechwriter, who wrote the eulogies for every policeman and fireman who died on 9/11, giving him “the dark distinction of probably writing more eulogies than anyone else alive.”

But you were drinking and having premarital sex, right? Isn’t that kind of an indirect way of questioning your faith? Is disobeying questioning? It can be, but I don't think I was really pondering questions of faith when I started drinking in high school, and the premarital sex didn't actually happen until after I graduated. I think looking back the answer is yes, I was looking at other options. But I didn't think about it in those terms then. I think lots of people of every faith experiment in these ways but ultimately decide to embrace their religion.
