it will be a hard journey if popularity is the goal of you being here. the two platforms apparently share distinct differences on how they technically works both on the protocol and the social itself.

X, unlike how it was back in the day is mostly on chasing fame or popularity so you could be "known", the same as many other platforms nowadays (YouTube, Instagram, Facebook, you name it).

Nostr in the other hand is more towards to having your voices being heard, So people can read what you are writing and other things. Fediverse fundamentally works nearly the same except it's a mix between the two platforms.
