Notes with the highest number of zaps from unique npubs. To clarify: I don't mean the highest amount of Sats for a single note. You could add an option here to only count zaps of npubs your follow.
Yes. The posts that are appreciated by the largest number of individual plebs. May also need some WoT function to eliminate 1-sat-bot-spam in future.
This would be a potential use case for the NIP-51 Grapevine WoT List. Two ways to do it: 1. Completely ignore zaps by npubs that are not on the list. or 2. Ascribe a weight to each zap, where the weight equals the Grapevine WoT Score of the zapper. Optional: make the weight an also function of the amount of the zap. Maybe weight = sats * Grapevine WoT Score.
