Apparently there's a social media site founded by ex-Twitter-employees called Pebble (formerly T2), and they say it's "the kinder, safer, more fun public square, enriched with AI."
They also say, "We look at your past social history to be sure you will enjoy Pebble, and then invite you in."
You have to have a Twitter account to request an invite. If you're not active enough for them, they'll reassign your username.
