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.
And that’s exactly what’s supposed to happen. Instance wars and eventual defederation and fragmentation are important moderation tools, and will progress the culture and feel of instances and regions of the Fediverse. Many instances will form federated [cliques](https://en.wikipedia.org/wiki/Clique_(graph_theory) that are highly connected and have similar vibes and cultures, and some will be federated with multiple cliques, showing users a variety of cultures and situations.
If the Fediverse reaches a large enough number of people, it can support multiple independant cliques, and enable users see entire mini-universes with different communities and vibes.
