Thus spake Zuckerberg: “We don’t think a modern messaging system is going to be e-mail.”
The Facebook founder said so in November, when his company unveiled its new messaging platform: a system, sans subject lines, designed based on the assumption that in the future most electronic communication will come in brief, informal bursts. In December, Zuckerberg’s prognosis was essentially certified by the New York Times, which ran an article suggesting that among young people who are in college or about to be, e-mail is quickly going out of style.
