If you're attending #FediForum let's have a discussion tomorrow around this open access paper: Governing Together: Toward Infrastructure for Community-Run Social Media which argues that decentralized platforms like the Fediverse focus on governing within communities, but ignore the frictions between them. From workshops with 24 Fediverse community organisers, they identify six design challenges (visibility of governance decisions, collating issue information, controlling what's shared and with whom, enabling new inter-community relationships, customising governance, and minimizing adoption barriers) and propose three principles for "inter-community governance": modularity (shared vocabulary, like governance nutrition labels) and forkability (copy and adapt others' governance structure or rules), and polycentricity (overlapping trust bubbles instead of one global network, i.e. archipelagos).
Decentralisation and autonomy alone aren't enough, communities need connective tissues to interconnect them beyond just technical federation (a mycelium network if you like 馃槉)
If you're interested and are able to read or peruse it ahead of time that will help us have a more grounded and potentially productive discussion based on it...
