Completely agree.
And there’s a key word you left onto, and it’s the one thing that will make or break the fedi, more than anything else: communities.
The core of any social platform or protocol isn’t the software, servers, or APIs. It’s the communities of people that use it.
Without those communities, even the shiniest of social media apps will fail. See Google+ for a real-world example.
So how do we build or attract communities of people for Lemmy?
Indeed. “Sense of community” is an aspect where additional socio-technical support native to the Fediverse can be quite helpful. We have the basics now. There’s work to add Groups support, but community is more than just groups. It has intricate and meaningful relationships between many other groups and people. Just like in real life.
