No women allowed?

Jason Kottke muses on the predominance of male narrators in historical documentaries. He explains that apparently "Authority is part of the issue, but in the narrative context, men are perceived as gender neutral, while women are perceived as female. Since the narrator is supposed to be anonymous and not perceived by the audience as a person, the more general neutral the better." Does this "gender neutrality" have other implications for new media in general? I'm thinking here of the "Where are all the female bloggers" question (which we'll discuss later in the semester) , but I'm also thinking about podcasting and journalism. Undoubtedly, Kottke's observation is applicable to news anchors and the like (hence the male dominance of that field). But does and can this phenomenon spill over into other areas of new media?
