No, it's not really Eminem on his Twitter account - he doesn't even know how to use a computer. The rapper told contact music that he was completely computer illiterate.
He says, "If I learn how (to use a computer), I'm going to be on that b**ch all day looking at comments about me, and it's going to drive me crazy."
He must be kinda exaggerating though, because he also says he watches youtube clips when his friends send them to him. So really, he must have an email account (though it could be aol) and know what youtube is.
Still, that is a poor showing. He'd be dust if he had to compete with Justin Bieber these days. As "Jacqueline" comments on the contactmusic story.. "Eventually you will be left behind in your old age if you don't learn how to use a computer.." We're just saying.
