On Twitter, people say things that they think of as ephemeral and chatty. Their utterances are then treated as unequivocal political statements by people outside the conversation. Because there’s a kind of sensationalistic value in interpreting someone’s chattiness in partisan terms, tweets “are taken up as magnum opi to be leapt upon and eviscerated, not only by ideological opponents or threatened employers but by in-network peers.”

Anthropologists who study digital spaces have diagnosed that a common problem of online communication is “context collapse.” This plays with the oral-literate distinction: When you speak face-to-face, you’re always judging what you’re saying by the reaction of the person you’re speaking to. But when you write (or make a video or a podcast) online, what you’re saying can go anywhere, get read by anyone, and suddenly your words are finding audiences you never imagined you were speaking to.

I think Stewart is identifying a new facet of this. It’s not quite context collapse, because what’s collapsing aren’t audiences so much as expectations. Rather, it’s a collapse of speech-based expectations and print-based interpretations. It’s a consequence of the oral-literate hybrid that flourishes online. It’s conversation smoosh.

Dornstein ushered me up to the third floor, where two cramped rooms were devoted to Lockerbie. In one room, shelves were lined with books about espionage, aviation, terrorism, and the Middle East. Jumbo binders housed decades of research. In the other room, Dornstein had papered the walls with mug shots of Libyan suspects. Between the two rooms was a large map of Lockerbie, with hundreds of colored pushpins indicating where the bodies had fallen. He showed me a cluster where first-class passengers landed, and another where most economy passengers were found. Like the coroner in a police procedural, Dornstein derives such clinical satisfaction from his work that he can narrate the grisliest findings with cheerful detachment. Motioning at a scattering of pushpins some distance from the rest, he said, “They were the youngest, smallest children. If you look at the physics of it, they were carried by the wind.”
