I‘m not sure if tribe is the segregation I want. It should be more about my current mode-of-mind:
Sometimes I brew beer, sometimes I want to discuss about Bitcoin, sometimes about nostr, sometimes about programming, sometimes about politics, sometimes I like to scroll, sometimes I like to know what people in geographic proximity are doing…
But always I want to know what person X is up to, what X thinks about a matter, and explicitly because this person is not in my usual tribe cluster. I like how facebook did it in the early days. It was about people, not content.
