It is interesting to contemplate a world where one social network like facebook didn't end up dominating the entire space, but instead we had a bunch of social networks each dominating their own geographical region. And each such social network had its own peculiar dynamics, features and product experience that reflected the culture of the region it dominated.
I think such a world would have lead to way more innovation in this space.
After all in our world the only region that remained independent of Facebook and developed its own form of social network, China, has definitely contributed its own distinctive take on social network design. For good or bad, no one can deny the contribution of wechat and tiktok to this space, with their take on economic design in social network or insanely personalised algorithms.
Now imagine instead of a bipolar world of social networks that we inhabit, we had a multipolar one with for example the Nordic, Latin American and African region each having their own thriving social network universe that reflected their culture, and it is easy to contemplate a much more richer and innovative social networking landscape.
