Not meaning this as a dig... But when people think #federated #forums is a "new idea", I feel really old.
This is like cycle 3 of federated forums for me: UUCP, then USENET, and now...
It seems tech moves in cycles of #centralization to #decentralization to centralization. We never learn the lesson "Don't put all your eggs in one basket."
Sadly, the cycle last long enough for everyone to forget about the old tech that did the job.
