Think of it like a nesting doll.

Instances have communities (or magazines).

Communities have posts.

Posts have threads.

I made a comment thread on your post to this community on the Lemmy.World instance. Other than the usage of instance for a social media type website, this has been the lingo of the net for several decades. You would have simply replaced “instance” with “specific website.” (Though the usage of “instance” to refer to a duplicate server has been around since at least the mid to late 90’s if not longer)
