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.
