According to the author of the Time article, Bill Tancer (author of Click: What Millions do Online and Why it Matters), Twitter’s largest age demographic is 35-to-44-year-olds. Of that demographic, the first group is, as Bill refers to it, “Stable Career” types: “a collection of young and ethnically diverse singles living in big-city metros like Los Angeles, Philadelphia and Miami.’ The Stable Career tends to work in the arts and entertainment industry, drive small cars and espouse very liberal political views.” Cross-reference that with Stuff White People Like and a case for a 100% match can be made: #47 Arts Degrees, #60 Toyota Prius, and #8 Barack Obama.
Bill calls the second largest group of the demographic “Young Cosmopolitan.” “These are the 40-somethings. They’re likely to drive a hybrid car such as the Toyota Prius, earn household incomes over $250,000 per year and also identify with very liberal politics.” Again with the Toyota Prius and Barack Obama–and it’s a given that white people have high household incomes so they can afford all the accoutrements of white life, of which there are too many to list here so you’ll have to read the book.
Then the final slam dunk: the fact that both these groups “appear to be all-around Web 2.0 fans”–you’ll need to check out #106 on the Stuff White People Like blog because it’s not included in the book.
I rest my case.
