I like this approach. A zap is equivalent to a like - but with a micropayment behind it. Emphasis on micro. The amount of money is negligible but also irrelevant. Maybe the amount NEEDS to be below what would trigger the thought-process behind a financial decision. By zapping a note, I acknowledge it. But maybe, just because the note made me giggle / smile / feel something - I dont HAVE to donate money to that person. The note brought me value by making me giggle, sure, but lets say the value lasted for about a split second. Nod. Approve. Acknowledge. Hit like on the note / but in nostr world we zap. Then there are posts that bring me value for more than just a split second. Maybe I learned something valuable or the note was a song or podcast or whatever, and my level of interaction with the post warrants a donation, then instead of my zap equivalent to a few cents I might want to zap a dollar or 5 dollars or 20 bucks. What value would a nostr post need to bring you for you to consider zapping 20 bucks?

why nod when you can

Well thought out. Few notes are worth that amount. But podcasts and music get them often
