In my former job, which I have had to ditch because the abuse I got from management and his gaggle of yes-men got too much and threats of pay-docking started getting thrown around, there is this absolutely gorgeous, vivacious lass from South Africa who didn't even start out thinking she was into this IT thing at all, and rapidly went from first line to second line, and talking about things that I didn't know about, and handling all kinds of problems that I would have been a bit lost at first dealing with.
I suffer from a problem in this business also - I am not 'professional' I write a lot of words and tend to be much too honest, apparently, to be a professional at these things. It is perhaps an equal impediment as it is for you as a woman in IT. Back in 2003 I had a girlfriend who was an avid geek, and she was a beautiful blonde as well. I personally don't see or make judgements like some of the epic blunders that you have mentioned in this article, whenever I have seen women in IT. I don't make judgements. I know that women in IT learn pretty fast to be humble and I don't expect them to show off their knowledge the same way as men in IT tend to do.
Things will change over time. In some cultures there is less of this blinkered idiocy than others, like in Russia and many slavic countries, a lot of man-dominated technical fields have a lot of women involved, mathematicians, engineers, logistics specialists, managers, and so on.
One day the average human won't be such a damned ignorant fool as they are now. Hopefully it won't be after we are dead.
