Eminem
In 2010, Eminem gave Spin his reasoning for not learning the ins and outs of a computer.
"Here's why I don't know how to work a computer," he said. "If I learn how, I'm going to be on that b---- all day looking at comments about me, and it's going to drive me crazy."
And even though he joined Twitter in 2009, in seven years he's tweeted only 615 times.
