Also I agree that subscriptions are a bad (easy to implement) model. Pay to post is the way to go. Dynamic markets determine reach baseline is 0.1 sat / kb. Your army of followers can repost at 10sat/kb expand your reach and duration. Signal wins. Nostr incentives are too heavily slanted to the content creators and not the infrastructure.

This will work well post onboarding. Pay to post will have a heavy onboarding setup that will disincentivize people and impact growth. Slow death.
Voluntary pay to post for free tier relay. Mandatory or subscription for premium relays with premium features like note archiving?
Clients would be wise to implement these payment rails since most have their own relays for performance and new feature compatibility. Will can’t be going broke on client development. It’s the Damus.io relay costs.
