Tools to make it as easy as possible to interact but I think there is a psychological aspect to it that necessitates something at the social layer to normalize the act of micro-paying for content.

Patreon but with zaps

Universal zap goals regardless of the client

Subscription models

Zap forwarding/splitting (customizable overall on profile + on singular notes)

Transparent sponsored notes, where you can see which user/company is sponsoring this specific note

Referral links for services/products, where you earn zaps per item sold, volume, subscriptions sold etc.

It is going to be a process of experimentation, and not every potential solutuon will be ideal for every content creator.

To start, the volume of content has to reach a critical mass to begin experimenting with different solutions.
