an experience better then just the rest of the crowd.
it can still be a paid app. ie nostr build is paid app.
signup can be made easier for those just wanting to use npub... & voluntarily a user can opt to provide email in addition to their npub. and ofcourse maybe provide flexibility to those that only want to use email.
im sick of using any other new platform or service where they notonluy already get my metadata (what i click on, what i like/buy/etc, ip address, etc) but also my cc data, my address, my email, my name, etc etc
sorry for the rant but im done with all new services that are like rest of the crowd. i will await for more of "the web 5" we are seeing with services recently (mostly around nostr)
