Just watching that crappy visitor counter go!

This actually made me chuckle more then it should have. Take my upvote

This could also be the gateway into instance transference. If the instances are more in-sync, it will be easier to transfer either a user account or a community.

Indeed, does it not make sense in a fediverse where you can forward or change your account to another instance a community, be it called magazine or lemmy can change instance as well.

It would also be a protection.
Already now we are seeing some instances of lemmy's / magazines growing larger than others e.g. selfhosted on lemmy.world vs lemmy.ml

Image in a year time if the largest of the communities would suddenly drop out (database corruption, server takedown, admin issue) again all the knowledge / posts are again lost and difficult to recover.

Or does it already work that way and I'm still not really grasping this hole fediverse thing?

There are some good ones with easy access like the dreame line! Otherwise a secondhand roborock S5. Mine has been going strong running valetudo for years
