Look at the average Nostr user’s notes and it seems to me likes far outweigh thoughtful replies or zaps.

Because often its not a person to person engagement. Like we are doing now.
If I posted a picture of my dog. I would likely get some likes and possibly a comment or two of someone who wants to talk about the picture.
Just as in real life if I was walking my dog at the park. Some smiles. Maybe a verbal engagement or two.
