Nostr is not social media, it's a protocol for decentralized applications of any kind.
I built the donation page for #NutNovember using NIP57 Zaps and npubx.cash. Using NIP57 allowed me to display a success message to the user, even though npubx.cash does not support LUD21 verify.
At the same time it makes the donations auditable and public. On https://nutnovember.org/donations you can see how many donations came in and what their total sum is.
