Huge fan of the cathedral view. It's the only thing that makes modding amazing.
In the parlor view, everyone is holding their secrets close to their chest and hiding the tricks, which means the community can't learn from each other nearly as well.
Cathedral is what allows tons of tiny contributions to add up to a vast amazing experience. Each person's work can be built upon by the next or used as inspiration and guidance for something new.
For an ecosystem built on people working after hours, this collaboration and knowledge exchange is fundamental.
