Web2.0: For men only?

I happened to be looking at digg.com's "about" page. There is there a collage of photographs of their staff. All but one of them are white men. The sole exception, Nicole Williams, holds the position of "Digg Ambassador" (which presumably means that she does public relations; I would not be surprised to find out that she is their receptionist). Her personal profile starts out by describing her as their "Rude Girl", and talks not at all about her professional qualifications, or even about what she actually does for digg.com. Contrast this with, say, the profile for Steve Williams, which talks in some detail about his other activities.

So, why is there only one woman at digg.com, and why is her job so vaguely defined?
