The fediverse is not a product. The fediverse is an organization of humans willing to interact together. There are dozens of softwares, documentation on how it works and how to migrate, tens of thousands of instances each with different rules. The fediverse is a universe, not a plastic-wrapped package you buy and consume. The goal is not to capture the population as fast as possible, as seems to be the only valid metric on here, because that would mean coming back to where we started and not having advanced a single step
> if you can’t figure it out you shouldn’t use it
If you don't want to take the time to understand what it is, then you maybe you shouldn't use it. It's like coming to the house of a stranger: you don't know them, you try to understand the rules, ask around, maybe remove your shoes at the door or at least make sure it's ok if you keep them. But if you expect to enter without saying a word, picking beers in the fridge and shouting at people that's just rude. The fediverse is built to prevent exactly that.
> these are meant to be replacement services for widely adopted social networks.
No, there shouldn't be a replacement for social networks, the same way the web is not a replacement for something else: the web is one application that equalizes access and publication. The fediverse is a universe for everyone to have a voice and discuss and organize. Make conversing easy by giving back control to people.
