Obviously, the weak point in that approach is the lack of discovery, which means that an instance federated by whitelist only could go from safe space to echo chamber real quick.
I have zero interest in a stagnated timeline of other near-50, white, cishet dudes. Which is also why I'm hoping to see more users from the smaller instances now that the deafening chatter from the big servers has gone away.
I only cut down the big oak to give space for the undergrowth 😉
