A brief history of women in computing

> Between men having spent some amount of effort and energy actively pushing women out, and marketing decisions having had some influence on creating gendered stereotypes, and those stereotypes having had some impact on diminishing appeal of the field to women, and workplace sexism, hostility and unfair treatment having had some deterring effects against women, and society-wide labor practice changes having some influence on women’s presence in the workforce overall, we have a very cumulative picture in the aggregate that explains the status quo for women in computer science.

This seems to me to be the key point in the post: there's no one reason that we can point to that would explain how we got to where we are. (I would suggest that trying to find that one reason is, in fact, counter-productive.) This being the case, I don't believe there can be any one way of "fixing" this -- the large change has to happen as a result of many smaller changes, including in hiring practices, standards of behaviour in the workplace, and in schools, colleges, and universities.

In other words, that small change that you can make that you don't think will make a big difference? It can.
