I guess part of the problem is how women are presented in the tech industry. Whenever you see women on a tech event they tend to be booth babes, or they have been send to the event to attract men.

I was at a career event last week. None of the women representing a company could give a clear story of what the company does from day to day. They where just there to be pretty.

If we want to stop sexism we have to stop this, but i don't think this will happen any time soon.
