Reality for mastodon, I think, is that the "migration" is basically over, and has been for over a year now. The Brazilian move to BlueSky (and not mastodon) highlights it very well.

Recalibrating on what we want and can do with the fediverse, as well as how central we want the mastodon project to be, are the best things to do now.

For me, it seemed like Gargron didn't really know how to speak about the lack of a Brazilian migration to mastodon in favour of BlueSky, and handle a new moment of actually dropping in popularity or perceived relevance (having been the underdog then rising start for a while), which I take as a cue that being the dominant center of the fediverse isn't a natural fit for Gargron and his project, to the point where the fediverse may have just outgrown it.

So, random thoughts:

• I think de-emphasising mastodon as the fediverse's big player and surest means of gaining users is likely a good idea in the medium to long term. Replacing twitter for twitter users is now something others do substantially better: Threads and BlueSky. While I'm not sure Mastodon, or its decentralisation, offers anything particularly novel, different or attractive. If anything, its lack of compatibility with other fediverse platforms is likely a negative.
• More broadly, a focus on microblogging is best de-emphasised, for the same reasons as above. Conspicuously, mastodon is the only platform that's really trying to replicate twitter-style microblogging. Just about every other platform tries to go beyond it in some way.
• Instead, IMO, community building through richer and more flexible platforms is what the fediverse should focus on, in large part because it matches what the fediverse's decentralisation actually provides: control and ownership over your community.
  • Indeed, I think the fediverse needs to kinda wake up to what it really is. So much of the advocacy during the twitter migration was pushing the idea that the decentralisation doesn't really matter (and "it's just like email") and can be ignored for the most part.
  • In reality, it does matter and can't be easily ignored. And the world has more or less realised that, with mastodon (and the fediverse) now suffering from a branding issue.
  • So I say the way forward is to accept what decentralisation is and either add an additional layer to polish the UX, or lean into it and build on it rather than pretend this place is something else.
• By community building, I mean "flexible space creation" that likely translates to a range of relatively composable features, structures and content types and formats. Basically, stop rebuilding big-social style platforms, and build "humane spaces" that more or less comprise any/all of the formats of the existing platforms in a way that people can use however they want.
• Unfortunately, this is likely not trivial, at all, and would likely require better organisation amongst those contributing to the fediverse, and perhaps improvements to the protocol itself.

As for the threadiverse (lemmy, piefed, mbin, nodebb etc), it's always struck me that group based structures (EG, lemmy communities) seem to work better over federation. Account migration from instance to instance is simpler, in part because the user is not the central organisation. Which instance you're on doesn't really matter that much. Also, blocking a whole community seems a useful middle ground between blocking a user and defederating a whole instance at the instance level, and ditto with community level moderation which can operate over federation. Additionally, the little technical talk I've seen on the issue seems to indicate that moving a community from instance to another might actually be quite viable.

If true, then community building might be best started with the group based platforms. Maybe an ecosystem of formats that involves all of them other than microblogging might work well?? Perhaps user-based content could take on a different structure from what microblogging does ... perhaps something like what BlueSky does could be adapted to fuse user-based structures into group-based platforms like lemmy (IE, your content exists in a pod which you can own and which is portable, which is then sucked up into various public feeds depending on what permissions you provide)??

Things like private communities, group chats, blogs, wikis (and RSS feed management?) intuitively seem to me to pair well with group-based platforms and community building.
