It is a good first step. I personally have friends on Twitter who unfortunateky have suffered from being shadow banned, so their content cannot be seen as much as they would like. Waiting for Elon to revoke shadowbanning, since it goes directly against he wants Twitter to be.
Elon claims that the shadowbanning is no longer a thing.
If your friend wants to have more reach, have them sign up for Twitter Blue. I went from getting a couple likes per post to getting a couple hundred likes after signing up. Social media has never been something I cared about, but I’m glad to participate in what Elon is trying to do and the evidence it’s working is crystal clear.
