Thank you @eest9 for mentioning pluralistic agonism! Your remark on instances as communities reminded me of Alan Kay who considered servers as the place for the community back in the days 
The talk finished with 4 questions from @eest9:
- Which aspects have I overlooked?
- Did this talk influence your perception of the Fediverse?
- Should we promote something of democratically ruled instances?
- How should we finance instances?
1. Overlooks
The presentation of the public sphere theory remains entirely euro-centric and quite academic, which is not necessarily an issue since it originated there and you include āpluralistic agonismā, but not before having presented the mainstream view of dominant culture which already removed/ignored/silenced a lot of other approaches (see for example https://www.eurozine.com/change-course-human-history/). Nevertheless, it does not affect the content nor the pertinence of your talk, so itās fine.
2. Influence
Not much, as I knew most of what you introduced here and mostly agree with your position. Iām glad you made this presentation for other people with less political background.
3. Promotion of democratic rules
I certainly support encouraging people to organize their community in self-aware, self-regulated collectives promoting fairness, open debate, and a more democratic approach, especially if we keep the scale of instances small enough to ensure this process is working well. We could certainly learn from various existing instances and their modes of existence, as demonstrated by Derek Caelin in Decentralized Social Networks vs. The Trolls. I would suggest the #fediversity is a good place to do it.
4. How should we finance instances?
My take is that it depends on the community using the instance. Some will be funded by their admins, some will depend on donations from their membersā¦ Maybe, as part of the previous question, we could also encourage best practices, such as maintaining awareness of the costs and current balance and create a two-buckets fund per instance: one for covering costs, and an extra overflowing bucket for solidarity, either for the instanceās community members, or to sustain wider Fediverse costs like development or infrastructure, meetings and gatherings, etc.
I would expect university instances to cover all the costs for their students and staff, etc.
