Mockup:

[alltheseas]

@BenGWeeks suggested a NIP should be utilized, or created if it doesn't exist.

@joelklabo suggested a new profiled field for pinned note, and that it is preferred to go the NIP route, vs Damus only implementation.

~It could be that pinned note relates to NIP-16 https://github.com/nostr-protocol/nips/blob/master/16.md Replaceable Event kind~

Snort social implementted using NIP-51. Check snort implementation
