This is what the article is saying there’s a waitlist for and it’s also going to be moderated. So how is it going to be different than Twitter?
I guess you didn't know about mastodon until now. I have joined there but social media isn't really for me, so I can't really speak for it: https://joinmastodon.org
I don't think it has a chance to ever be as popular as twitter, simply because they don't want to add features to make it addictive.
