I'd agree with @samplereality. The Federative model and its implementation in ActivityPub and the Mastodon UI and API constitute a significant paradigm shift. That there are fields for CW and choices about visibility from the start are significant, as is the choice to eschew non-temporal weighting in timelines. All this creating a heterarchical environment where heterogeneity, niche interests, variant cultures, etc. can experiment and develop.
Will academic institutions or their components set up their own instances?
Will scholarly communities congregate in instances, as some #histodons have been discussing?
Will easy account transfer from instance to instance allow project-or-discipline-oriented instances to wax and wane with less fallout that abandoned blogs and websites?
Oh, look, there's one now: https://c18.masto.host/@carrideen/109270450287627832
@[email protected] Yes, mastodon.social is really overcrowded! Any #histodons with an interest in the 18th century are welcome on my fast new little instance, c18.masto.host! I found it very easy to set up and not too expensive for a midsized server. Migration instructions: https://c18.masto.host/@carrideen/109263805567073435
@samplereality It's an interesting aspect of the whole thing isn't it? There's several folks in the fediverse who maintain two or more accounts, each with a different emphasis. I just had a follow, for example, from an account that's one of five operated by a person and that one is "exclusively for shitposting".
I'm feeling some constraints at scholar.social, but so far I think visibility levels are all I feel I need to manage varying types of discourse. But we'll see.
