finally read "The Tyranny of Structurelessness", recommended by @bisimilarJames

in short
- every group has some structure
- if not acknowledged, it is informal
- if it is informal, it can't be held accountable
- acknowledged and publicly described structure is better, but not perfect & existing models can be exclusionary
- accountability is critical to accessibility
- allocate tasks according to abilities, allow people to learn, and rotate who does what
