It can't be just about making women more visible. The girl scouts did a study and the most common reason high school girls didn't want to study STEM fields was because they'd have to work harder than men to be taken seriously. Seeing other women can help, but even more helpful would be seeing men take those women seriously and publicize their work day-to-day, instead of just when trying to encourage girls to consider their field. Right now, young girls may be accurate in assuming that entering the field will suck more for them than their male friends. It's not like there aren't plenty of alternatives: digital archiving and computational biology, for example, are non-male-dominated programs coding-inclined women can pursue instead. If we want rational people to join our field, it has to be the best choice out there.
