I work in IT.  There are no two ways about it, it's a man's world.  Not to say the few women that do work in IT do not hold there own,  because they do in every which way.  They are usually the cool headed, logical thinking types that use applied sciences in their every day life.  The thing about applied sciences is not a lot of women would choose that path in school from what I have seen.  In my university years there was about the same ratio of women in my classes as there are in my now IT work life.

If there was a 50% female enrollment rate in University or College IT courses and then only 20% that were in the industry there would be a problem.  That just isn't the case.  Nursing would show the same results in male ratio's of schooling to hiring.  

I think Google should be sued by this gentleman for improperly firing him.  Google took the low road and should apologize.  HR departments have become detriments to business.
