These are good female tech role models - apparently

The UK's Evening Standard has an article tonight about women in tech [1], and as role models suggest Nicola Mendelsohn, Joanna Shields, Marissa Mayer, Dawn Airey and Sheryl Sandberg. I am curious: how many of these are role-models for getting hands on with tech and working as a developer/scientist/engineer, vs being a high-ranking director in a management role? I do not know the women mentioned but they seem at odds with the thrust of the article. It's a shame they didn't talk to female programmers... 1. http://www.standard.co.uk/lifestyle/london-life/maggie-philbin-silicon-skirts-were-still-very-much-an-exception-8962022.html
