Cool, but I use the zap button as a like button now. The algorithm is failing if it isn't accounting for people like me. It seems to me that the most valuable posts are the ones that generate actual value. Otherwise, you're just focusing on what a particular algorithm considers valuable. A like costs nothing. A zap costs something real.
You could get a million likes and it means less than a single 21 sat zap unless the post is leading to increased income in some other way. Zaps kind of complicate things here because it's possible for very few zappers to theoretically add more value than a lot more likers. And some people could do both. It's tough.
