From the Washington Post:

Tomek Kott is so stubborn about not joining his friends — in truth, nearly his entire generation — on any social networking site that his wife launched a mini-crusade against him. Exploiting a tactic surely befitting our times, she whipped up a Facebook group last year called “Tomek Kott Must Join Facebook.”

…

“I am old-school in the personal touch way,” said Tomek Kott, who lives in Silver Spring and has outsourced many of his digital communication duties to his wife, Anne. “All my friends from high school have also met my wife, and they’re friends with her; my wife ‘friended’ them or whatever it’s called.”

Kott and others like him are social networking refuseniks: people in their 20s or early 30s who have gone off the grid, eschewing the ecology of Facebook, Twitter, MySpace and the like. In Washington, refuseniks are not exactly operating in isolated, Luddite worlds: One is in a dance company, another is a rapper/hip-hop singer, another is a Georgetown undergraduate. Kott grew up in Redmond, Wash., where his father is a software engineer for Microsoft.

…

The vast majority of their peers in the millennial generation are social networking pros: About 85 percent of all Internet users 18 to 34 visited Facebook, MySpace or Twitter in August, according to ComScore, a Reston-based Internet data research company. And about 84 percent of 18- to 29-year-olds check social networking sites at least once a week, according to a May study by the Pew Research Center for the People and the Press.

I find that 85 percent number to be extremely high. Whatever it is, I would think that there’s a few people out there that say they check the sites, but don’t really do because they want to be in the “in crowd.”
