People are basically looking for a standalone Facebook groups that's not owned by a corporation. Or Twitter for small groups but not what mastodon has become. I think honourably some people have tried and many continue to build niche products like micro.blog. Personally I just want a service that is not commercially owned, for profit or by a US corporation. My own attempts/ambitions get in the way of being able to achieve it, so I started working on something that slowly solved my own problems e.g news feed aggregation, videos without shorts or the algorithm, chat with AI based on a model from Qatar. Soon I'll add posting but only because I feel like I need some sort of personalised way to bookmark and share my thoughts within it being about gaining attention or validation from a world of likes and retweets.

There are no good answers, because the reality is the next medium is probably quite different from the last. But yea personalised small group chat, feed, news makes sense.
