Diversity is a must. In the past year we made a few decisions that we had to roll back again, which I could directly attribute to lack of diversity in our module.
Blender is for everybody, and I want everybody to feel welcome to be an active part in the community. And that also means being part of module meetings, where decisions are made. For example the decision to remove a feature nobody is using -- guess what, people _were_ using it, just nobody from our group. Diversity would have helped.
