I honestly do not mind it one but. I quite like the interface. It’s minimal but there are some bugs to it which is to be expected. I really do like the overall design of it though. There isn’t too much going on. It’s like old Reddit which I am a big fan of
An instance can crash, close down or somehow disappear at any time, and if that happens all the users, communities and content in those communities from that instance is lost forever. Right?
I would guess that the copy of the community that this instance cached (starting after the first subscription to that community by a user if this instance) might persist. Anything from before that time would be gone, at least from your perspective.
This is my interpretation but I don’t know for sure.
