I loved reading about creating simple protocols that fit on a napkin in ,, Where Wizards Stay Up Late: The Origins of the Internet''.

I feel the same way of nostr right now as a decentralized alternative to Twitter. It's super simple and there's nothing to take away from the basic protocol:

I think it's time to get back to developing these kind of simple protocols that incentivize a healthy competition between clients and servers (and maybe other participants).
