Setting aside the subjective nature of “better” and “experience”, I’m curious what platforms you’re referring to?

Also, (while semantics are generally annoying), nostr is a protocol, not a platform. Meaning that any number of platforms or experiences can be built on nostr, or brought to nostr, and plug directly in to the tech, user base, etc., which can’t be said of any other (purportedly) decentralized communication systems that I’m aware of. Protocols > platforms, etc etc 

(I recognize that I am obviously am a huge proponent of Nostr, and biased in that way, but it’s because I have had an unparalleled experience here, and so it’s simply honest when I say I believe this is the best, most robust/resilient, and enjoyable option out there).
