This is great. This is how it always should have been.
Organization of any kind needs a Twitter page or subreddit? No, they need their own official, self-controlled Mastodon instance anyone can see and listen to and interact with, even without accounts on that specific instance. They need their own kbin or Lemmy instance to make and administer their community on and have control over, everyone can still participate even without signing up for accounts on that specific instance.
