New MySpace Music chief Courtney Holt is a dude, okay?I feel sorry for Courtney Holt. Partly because the MTV executive is rumored to be taking a terrible job running MySpace Music, a feature of the social network masquerading as a separate company. But mostly because of his name. In a previous article, I was enough of a bonehead to refer to Holt as "she." Trying to do my part to promote the role of women in the tech industry, okay?
