Really good points guys! I'm one of those people on twitter where almost nobody reads what I tweet.
What's excited to me is this: Nostr is free speech, Twitter isn't. Now they are aware of that at Twitter headquarters too, so they're moderating less at Twitter. Otherwise more people come to Nostr. So even if not everyone moves from Twitter to Nostr, the existence of Nostr is forcing Twitter to have less censorship. 😀
