On the Damus app there is both the 🤙 action and the ⚡️action for a note (depending on the ops profile settings). My understanding of a full zap is that there can be recognition of the amount sent and therefore the cumulative everyone has sent (e.g.⚡️6.5k). The cumulative is shown so a note can be seen as having value.

This is separate to navigate to a user’s profile and using the ⚡️ there.
