I heard once that the case for which instance (for any federated app, be it Lemmy or Mastodon etc) on which to sign up is to choose based on “administration” not subject. That is to say, it is better to experience the fediverse through moderation and other administrative decisions than it is to do so on a server that is “subject based.” Thoughts?
A consideration is to check which instances are blocked. (See the instances link in the footer to check) to ensure the server doesnt block a specific instance you want to view.
