I had never heard of Reddit, let alone knowing that it was a major social phenomenon, until two of my students asked if I would do a Reddit AMA [Ask Me Anything]. I did the session in my office with two of my students guiding me, kind of the way I taught my grandmother how to use this newfangled thing called an answering machine. That evening I got an email from my editor in New York saying: “The sales of your book just mysteriously spiked. Any explanation?” It was all thanks to Reddit, which I barely knew existed. Another is a kind of innocence — though that’s a condescending way to put it. It’s a curiosity about the world untainted by familiarity with an academic field. It works as an effective challenge to my own curse of knowledge. So if you want to know what it’s like not to know something that you know, the answer is not to try harder, because that doesn’t work very well. The answer is to interact with someone who doesn’t know what you know, but who is intelligent, curious, and open.
