A fork of Mastodon is Fedibird, with features more like Twitter. https://github.com/fedibird/mastodon
The lead developer is @noellabo .
The Fedibird site looks to prefer Japanese writers. https://fedibird.com/explore
If anyone knows of English language Fedibird instances, perhaps we could help others to find them.

Is it written in Ruby too? I don't think Mastodon will scale well because of Ruby. In the early days the Birdsite was Ruby and it had major issues with downtime until rewritten in a l coding language that scales better.
