Thanks for the comprehensive comments. I didn't even know the whole backstory behind ActivityPub. I always just took it for granted. I think we agree that there are quite some issues that are technical in nature. I think we'd need so solve a few of those before we can think about growing the Fediverse substantially. It's certainly not easy. But adding drama also doesn't help. I'm quite pisitive about the Fediverse. At least in the mid to long term. Maybe a bit competition and new projects will help add a few new ideas.
