What an annoying article!
If you're pushing the agenda of 'more women in IT' then you are, by definition, not applying the rule of 'the best person for the job'. The stupid thing is that what you are therefore promoting in this article is the idea of sexual discrimination.
Honestly, if a CIO in today's economic climate is sitting around being 'thoughtful' about the ratio of men and women in certain roles then they are wasting time. There are a million and one more important things they should be spending their brain power on.
I'm completely with g434murray - why is it we don't ever see articles about how there's a gender imbalance in nursing, secretarial work, or teaching?
