It certainly needs an experimental phase, I was just doing research and checking out instances and whatnot first few days. You might find this tool useful for browsing instances and communities: https://lemmyverse.net/

Not too late at all. To change instances however, ypu need to register on that instance and do a new account. There isn’t a way to switch instances on one account. Many are hoping there will be at one point a functionality to export stuff from one account to another but I have no idea how realistic that is.

Looking forward for the inevitable legendary lemmy posts sometime down the line and me being able to say I was there for it.

I heard about horses dying from the stress caused by fireworks. It can also be hurtful to wildlife.

I’ve read this is coming in next release I think
