What flows into your feed,especially the global feed & who sees the notes you write depends on which relays you use. At the moment, it's all experimentation to see which ones work for you. A combination of free & paid relays seems to work for most people - it also depends on which client you use

If you're new and don't want to pay for relay subscription yet, I'd suggest

wss://nostr.mom

wss://nostr-pub.wellorder.net

wss://nostr.wine

(Wine is a paid relay but it's free to read posts from)
