Though the definition of community is not clear, we absolutely are a community but it is a matter of what metric you maximize for community detection. Nostr users currently share the same house (or street block) even if some never interact because they are always in different rooms.

Our nostr universe exists mainly within 20 or so popular relays. At the two extremes you have n communities of size 1 or a single communtity of size n. Extremes are uninteresting so we want to encourage moving towards the space in between. (Hey, found a shared value 🙌)

In between we have communties that are representative of IRL groups, where groups are very small. You also have high mixing of clusters where individuals mix among many small friend networks (Marie, Sikto, Samecat, Dan for example) where they are one of the tighter nit groups but globally spread out .

The largest scale of interaction comes from the relays we choose to interact with. But its not hard to imagine similar relations and communities can exist at many scales (social network, power law relationship)

All just an argument to say that nostr is or contains communities any way you slice it.

Acknowledgeing the scales of social clustering should be a priority and having levers to filter our feed at various levels of resolution should also help the dynamic of users who are unaligned. They are on the same relays because thats whats available, not because they care about the other users. Tools like this could help multiple parties coexist on the same relays even if they will always go at each other. Everyone will diffuse and segregate into their own communities, the original will still exist, just in a more opaque fashion.
