Day 2 here, and I can see the growth already. Personally I really like the notion of how its gonna shape up in the future but at the same time I really feel for the average user as of now its too complex to understand the working and how the cross servers thing is working. I mean yes still early days, UI will improve further leading to a better UX but the core mechanism yet is little tough to get along. For instance, still unclear if I made the right choice by signing up on lemmydotworld why not lemmydotml , beehaw etc… and where does this stop? like in the coming times i it would be like a thousands of servers lemmy.this lemmy.that lemmy.etc or anything.anything. That’s soo confusing for someone who just wanna join a server. Would be interesting to see how “signup anywhere, its the same thing” evolves.
On Mastodon there’s a self-destruct command that in theory deletes your content from all of the instances that are federated with you. I thought the same command was on Lemmy but it might not be the case.
Then you would be right that the old posts should remain on the federated instances.
