The term vote implies the action carries one of two values but zaps give you also magnitude so it tells you more. That alone means “vote” is not the right word. On top we can react with emojis each of which carries information distinct from “yes/no/abstain” so again I think “vote” is not the right idea. All that said, haven’t thought about a better label. Just wanted to add that it’s more than just semantics 😅

Zaps are payments like a tip. If it was a vote based payment then it’d be a bribe.

I like the term favor, but that only makes sense when constructing a model of quantifying relationship quality between npubs.
