I think the best things I get out of using at this point relatively buggy, slow, user-hostile ecosystem like Nostr are:
1) Feeling of freedom. Not walking on eggshells and being afraid of shadow-bans or deplatforming.
2) Feeling I am on fertile ground which is already producing a lot of growth, not just platform owned by one team and dependent on right and wrong decisions of aforementioned team (like Facebook, X and other old school corporate social platforms).
When I use Nostr, I feel like I'm following the wisdom of «skating to where the puck is going to be, not where it has been».
