If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that’s for the future of us all.
The important thing here is to get back to social networks and away from social media. The important entities here are the humans, not the memes or the money or the uplems or whatever we eventually call them.
Humans connecting with humans in ways that advance our collective well-being is the promise of social networks that Facebook and Twitter started. Once they saw how many users they had (and the bills for hosting and coding) they got hyper focused on making money.
Hypothetically we can avoid that fate here by having the job of hosting and coding spread out among many. Especially if we also come up with a way to crowd fund the costs of hosting and coding.
