Most will probably start with damus. And most people equate tech with the UI front end. But nostr, given its ethos and the fluidity of development in clients, is a good reminder that layers and protocols are where the magic happens. The UI is secondary if the thing is to last.

It strikes me as a bit of an internet time machine, warts and all (like difficulty of use, uptime). After a burst of open, interoperable protocols in the early days of the internet, we've been living through a 25+ year period of proprietary user interface and tech, the goal being to keep eyeballs on your site to sell ads. This is like going back a few decades to watch the development of a basic internet standard, designed to be interoperable, designed to be open, designed to scale to do who knows what.
