I don't "like" notes, I zap them. There are npubs that haven't setup a wallet that have no idea I appreciate their content.

Zap mode only on Damus
Some of us don't need money and don't want to be tracked.
I “like” notes as a way of acknowledging that I have given some of my time to read what the person has written or posted. That doesn’t actually mean that I like the post. It’s just that there is no way for the poster to know what their reach looks like. Value is different. That is when I zap. Value is personal. A different way to express appreciation.
