everyone has different styles and amounts for zapping. for example, maybe i zap 21 sats as a like. maybe if i really like something, i'll zap 000. if it's great content or something like that then ill do 10,000 sats. absolutely amazing content, 100K sats. we don't always have to zap "dust" as you said. it just depends on the type of content that you're zapping. either way, it all adds up.
