In the New York Times this morning:
The problem with e-mail, young people say, is that it involves a boringly long process of signing into an account, typing out a subject line and then sending a message that might not be received or answered for hours. And sign-offs like “sincerely” — seriously?But seriously, does anyone expect that an e-mail close with sincerely? Wouldn’t such a close mark the sender as quaintly out of touch with the conventions of the form?
The important point here though has to do with expectation and attention — the expectation that you, no matter where you are or what you’re doing, are ready to pay attention to me: a customer-service model of human relationships.
