Displaying the $ monetary value of every post is not a good look IMO. Zaps are already turnoff for would be Nostr users who don't subscribe to the capitalist view of monetising every human relationship and spoken word. Speech should be free and it should be seen to be free. Nostr will fail if it alienates socialist leaning people (which is the vast majority of people under 30 in the US). Young tech millionaires, much as I respect them, don't understand they are not representative of society. Nostr needs to be appealing for everyone.
