Well, still trying to figure this all out but I understand a LITTLE better now. Seems like Nostr is compromised mostly of Bitcoin lovers which is honestly kinda cringe so I'm hoping it gets more popular. Questions I still have: 

Is Zaps just Bitcoin?
How exactly do relays work? 
How do the communities interact with relays? 
Is a community the same as a relay? 

These may sound stupid but I have zero previous knowledge of any of this stuff. I'll figure it out.
