@Edent when I read the point about running instances on mobile phones my mind went to #secureScuttlebutt, a peer-to-peer social media that has no servers and as far as I know isn’t compatible with activity pub.A few years ago I was looking into it and I found it really interesting albeit with a few aspects that made it not too practical. If we truly want to go fully decentralised (I’m not saying it’s a necessarily better) that approach makes more sense to me securescuttlebutt
