The problem historically in computing has not been a lack of friendliness toward females, but a lack of females.

Back in the 1990s at the dawn of the Internet, 'We have a girl!' was potent advertising-copy, and has been pretty much right down the line in the broader Computer Science & Information Technology field.

From the ad-copy, we could prove scientifically that females constitute in excess of one full magnitude greater percent of the Internet work force, than is actually the case, even by the most-optimistic estimates. A willingness to be seen as accepting has not been lacking.

We've had various statistics posted from time to time, and although the context & upshot varies, the take-away has long been that females are severely under-represented in the emerging digital culture. Even though shops have generally been happy, even avid, to have them.

But take heart. Females were once drastically under-represent among gun-owners, too. Today, gun makers cater directly to them. Shooting-ranges rely on their accelerating presence to stay afloat in the recession.

It's a cultural thing, I think. Once upon a time, there just wasn't much of a cultural context to interest or draw females into the computer-game. Or firearms.

Guns - and other metrics - show that that can change, even where you might think it most unlikely. But you'll notice that Glock females tend not to wear NRA badges on their hat ... and there is a message there.
