The topic shifts on nostr from week to week in my experience. I rarely see nostr talk other than software devs talking about what they are doing. My feed is bitcoin heavy, but only about 20%. The other 80% is anarchism, sovereign living, personal commentary, philosophy/metaphysics, politics and general news. It pretty much keeps my funnel full. If you're trying to follow "important people"/normie-intellectuals, you're on nostr way too early for that, though we will take all we can get to build the network effect.
