I challenge you to find a single woman in this picture. It’s a shot of the keynote speech audience at last year’s MacWorld Conference and Expo in San Francisco. Are there really no female technology professionals in Northern California? I find that hard to believe. Why do you think this photo shows only a sea of dudes? It could be a shot of the priority seating rows in the audience. You have to pay a minimum of $1,495 to get those seats. Perhaps there aren’t any women in high enough tech positions at the few companies who can afford these passes. Maybe that’s why those companies are so successful! Then again, maybe it’s just that only a guy would pay $1495 to see something you can get for free on the Internet.

I bet there were a few women there, its just the picture is not showing any. I dont think its true that men earn more than women, maybe they are just more interested in that type of thing whereas women that are, are few and far between!
