@Sync when fiatjaf on Open Markets podcast ?
BTW, amazing podcast! Not sure if fiatjaf ever listen it.
I would like to hear a discussion about introducing on nostr a way to "pay to reply" to a note.

Think about its benefits and situations where it could be applied. For example, @Oshi can post his notes about stock and people that want to buy it, just pay the price to reply with a simple note saying their intention to buy and later send on DMs the delivery details. Or even make the reply private by default, or make it to be posted only on a specific private relay that only the OP can see it or is his own relay. This way people can reply with their delivery details directly.

This "pay to reply" can be also a good way to keep spam away (what fiatjaf was referring to some weeks ago).
