Since their early adolescence, they’ve learned to modulate their voice to address a set of listeners that may shrink or expand at any time: talking to one friend via instant message (who could cut-and-paste the transcript), addressing an e-mail distribution list (archived and accessible years later), arguing with someone on a posting board (anonymous, semi-anonymous, then linked to by a snarky blog). It’s a form of communication that requires a person to be constantly aware that anything you say can and will be used against you, but somehow not to mind. This is an entirely new set of negotiations for an adolescent. But it does also have strong psychological similarities to two particular demographics: celebrities and politicians, people who have always had to learn to parse each sentence they form, unsure whether it will be ignored or redound into sudden notoriety (Macaca!). In essence, every young person in America has become, in the literal sense, a public figure. And so they have adopted the skills that celebrities learn in order not to go crazy: enjoying the attention instead of fighting it—and doing their own publicity before somebody does it for them.
