When I was growing up in the U.S. in the 1970s, 35-40% of an average nightly newscast focused on international stories.

[According to Twitter] 24 percent of American Twitter users are African-American. That's about twice as high as African-Americans are represented in the population.

The wider world is a click away, but whether we mean to or not, we're usually filtering it out.

Curators are great, but they're inherently biased. Curators are always making an editorial decision. Those biases have really big implications.

The Internet is corporations all the way down.

If I use Facebook to stay in touch with my high school friends who are church-going Republicans, I may be getting more ideological diversity than in hanging out with secular progressives on the World Politics sub-reddit.

I fear that I can no longer travel without technology. Twenty years ago, I loved getting on a bus in West Africa and taking off for a city I'd never been to before, relying on advice from out-of-date travel books and fellow passengers on the bus. Now, I end up using TripAdvisor, Yelp, and Google Maps. I probably eat and sleep better when I'm on the road, but I miss the mystery of travel when it was more random and unpredictable.
