The instance a user joins is quite important. An instance that doesn’t want to store images and video will not want users who subscribe to all the image/video communities (that will federate their content over). A user whose interests are overwhelmingly technical won’t be interested in local communities on an artist server, where a non-technical user might feel at home. Many instance moderation policies are friendly to right-wing and will be defederated by mainstream instances. And then there are loli/shota/koda instances…
I joined lemmy.ml because the join-lemmy site gave me extremely little to go on. It was a coin toss between this and beehaw.org once I realized how few instances were established and not right-wing.
That was only 2 weeks ago and already I’ve seen the site force 2 server upgrades, even as the admins have strongly encouraged new users to join elsewhere to prevent centralization.
The instance list desperately needs a few columns added, including whether new signups are encouraged or discouraged.
