With broadcast enabled, your event is automatically re-broadcasted to the listed public relays when you post.

When you load your global feed, we only load content from your follows+their follows.

When you click anything else (like a note or someone’s profile) we load EVERYTHING we have unfiltered from the archive node. This should include replies and meta data from people who are not on common paid relays. You shouldn’t be missing (much) content and you’re also broadcasting to the world!
