I think jbattle might have meant that you're exposed to a lot of articles about promoting gender diversity in CS since you follow CS/startup sites (such as HN). If you followed sites or news aggregators for fields where the gender distribution is reversed (nursing or psychology both come to mind), you might see some of the same concerns raised about the lack of male participants.

ETA: Just saw jbattle's post - guess that's not what he meant! Sorry to have spoken for you :)

Ah yes - I read too fast, sorry
