Django only has 1 woman contributor

Looking here: https://github.com/django?tab=members there is only 1 woman allowed to commit to django.

After the last 2 lynch mobs powered by two core contributors of the Django community, I got curious about how inclusive their group of developers actually is, since they criticize companies like YC about their percentage of women founders.

Why do Jacob Kaplan Moss and Alex Gaynor think its so easy to find and include women programmers when their own community has only been able to get 1 woman committer in the 8yrs it has been around? (Same length YC has been around).
