Interesting fact: Since I started to use #nostr I mirrored 95% of all posts on Twitter too and vice versa. (Some videos I couldn't upload so I posted it only on Twitter as well as some unique retweets, same goes for nostr)
Yet, I've got about double the followers here since the beginning of this year compared to Twitter I used since 2009.
The level of shadow-banning, disadvantaging non-blue-checked users and other totalitarian practices of that network are so obvious in this regard. 🤔
I even remember having tweets which were deleted without any notification or reason.
To be fair the smaller size of nostr also probably helps. On the other hand decentralized nature and public/private key structure makes the user discovery orders of magnitude harder than on Twitter. So all things considered it's probly even anyway...
