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?
