When I was learning of ActivityPub a year ago, I thought: “There will be time when small servers will have troubles existing, handling all this traffic”. This thought is not written anywhere, but I truly believe I thought so.

I guess now's the time. Merveilles are 500:ing, and it's not even small!

What could be a different federation protocol that scales better? I'm not saying the Fediverse should migrate to it, I'm just wondering. In fact, I'm pretty fine with Fediverse getting this big.
