This news doesn't lack a hint of irony:
Former Twitter workers create their own instance on Mastodon https://macaw.social/about

#Mastodon

Macaw-Social

A small server by some ex-tweeps mostly for other *tweeps and friends.

Mastodon hosted on macaw.social
@alejandrobdn Had to happen! Convenient that they had everyone's personal email address to invite them. https://nitter.it/ZoeSchiffer/status/1591152301817102336
@nemobis @alejandrobdn unfortunately (we know people who got the email) the BCC wasn't to an actual full personal email list, it was to a Gooble group that didn't control who could post to it. Subtle difference but important to the story.
