I prefer people responding to my notes instead of liking, and that's where I would like to see the swap happen. For me zaps are for stuff I got real value from, or otherwise enjoyed very very much.

I think of the "like" as multi-purpose, demonstrated by it being different icons.
In the case of replying, it means "+1" to your post.
I guess the Facebook wonderbar or whatever TF it is called is pretty useful, even if it's not the icons I would choose. Remember when the only response you could give to a post about a school shooting was to "like" it?
Yeah that's pretty dark. I have no idea how facebook functions these days. Are you saying more icons would be better than less icons? More icons, more nuanced reactions to notes? Is that what you are saying?
