Looking to getting into developing Bitcoin, lightning, Nostr. Anyone have any good places for me to start looking for projects?

Can someone help me... why does paying for relays improve my Nostr experience? I still see posts from everyone I follow on the global relays correct?

I can't help but think forward anytime something new like Nostr comes out. If Nostr continues to rise in popularity, what other applications will be built using the protocol? some examples I can think of off the top of my head: - Video streaming service (Decentralized YouTube) - Tutoring/educational/coding support apps (Similar to Chegg.com/stackoverflow) Other Ideas?
