The best part of Fediverse is that unlike IRC it does not bind you in any way to any existing community or its rules. Which sometimes does have its charm, but sometimes are just a way of patronising and exercising tribal pressure.
The only thing that should be actively promoted and announced on every step is the fact that you can and should run your own instance, because this is a completely novel concept for those coming from walled gardens.
Also, if everyone just jumps on one of the few popular instances, we’ll end up with a social media version of Bitcoin, actually controlled by just a few massive pools in just a few countries.
