As a lonely teenager growing up in Virginia, I fed off any pop culture that could show me different ways of being from what I saw on 'The Cosby Show' reruns or read about in an Ann M. Martin book.

It took me years to find a program that kept me in shape: Gyms felt intimidating, and women's magazines seemed tailored for toning the bodies of already trim white women.

In America, mixed-race identity tends to invite both curiosity and suspicion, largely because few have found a way to interrogate it without centering whiteness as the scale by which to evaluate blackness.

The American understanding of China is filtered through years of politics; we rarely see the culture on its own terms.

When you're writing for the Internet, you have the analytics, and you know that people are bailing every second. But various people kept reminding me that once people have bought a book, they're in. You don't have to be selling them on every page.

I would like to spend my next two years showing how the aim of making technology available to every young person can be built into the effort to make our nation more secure. That is my latest concern and what I will be pushing over the next two years.

I believe that our Vuse, the digital vaping cigarette, is a game-changing product, and I believe that it satisfies smokers significantly better than anything that is on the market today.

I really don't spend any time on the Internet, so I guess I live a little under a rock in that respect.
