Sometimes when I use another Nostr client meant for the same purpose (such as microblogging), I feel like I'm cheating against the one I normally use.
Of course that's silly. But the experience just shows that the protocol is decentralized and user-centric -- it's not meant to tie us down to one centralized platform.
I hope Nostr developers continue to make strides in their great work. It's already cool; I just want it to be extra, extra supercool in five years.
