"Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates."

I am confused 🤯
Does this mean that posts just go into the void when no home relay is configured?
I wasn't aware and currently have not selected a home relay.
If it is the case, shouldn't there be a default configuration? 🤔
