SNorthern California is an enlightened haven of multiculturalism, and globalization requires a diverse workforce. Unless you're a startup, in which case you're going to hire people who look like you. Take, for example, the workforce of Automattic, the maker of WordPress, a blogging program.The company, founded by white male Matt Mullenweg, has just increased its white maleness with the acquisition of PollDaddy, a two-white-males Irish firm. Are we being too harsh on Automattic? Should we give it credit for not being 100 percent white and male? After all, Google prides itself that 32 percent of its employees are women; that it views that level as an achievement shows how imbalanced Silicon Valley's scales of equity are. Still, look at the Automattic company photograph, taken at a staff retreat in Breckenridge, Colo. If I were a woman or a minority working at this company, I'd hide in the corner, too.
