Think of nostr as like passing notes in school. Relays are the ppl sitting at the desks in between who "pass it on".
My suggestion is use the nostr.wine relay. It's a paid relay (you have to pay to use it) but it will connect with other relays so it's like an all in one solution. Instead of connecting to 10 individual relays, connect to the wine relay and it'll blast your notes far and wide AND retrieve notes from other relays you're not directly connected to.
See below for long winded explanation on zaps. TLDR zaps are peer to peer bitcoin micropayments.
