Why communities forks are bad? Less debate? 

 Yes, homogeneous thinking leads to echo chambers and polarization of views. 

 That's very hard to deal with, it kills many good cooperations. I admire people with social skills to avoid that, I wish I could learn how. 

 Some bitcoiners are balkanization fans. They dream about a Europe with 4285 states. 

 But we didn't do it, algos did. 

 And bot farms, Russian and Chinese also play a big part. 

 so instead of languages separated we have social media separated.
always the same I guess. 

 walled gardens 

 Sad! 

 What other networks have people gone to? 

 Is balkanization of culture the problem per se or the fact that it's happening within a monolith centralized governance? 

 Does Nostr fix this or not? 

 Honestly, I think social media in general is the reason for the acceleration of polarization. People don't talk to each other in person anymore. This leads to people forming opinions about the world based on their online interactions, where people are more hostile. And that leads people to be more xenophobic. I think if people spent more time talking to their neighbours than they did on social media, we'd be less divided.
