Tom is a user on octodon.social. You can follow them or interact with them if you have an account anywhere in the fediverse.
If you don't, you can sign up here.
So qq - can I sign into any instance with same login details?
@tommoor nope. I wish. You need to cut a hole into each server's walled garden.
@xori hmph, well that diminishes the idea somewhat :thinking:
@tommoor indeed. You can remotely view and follow individuals from remote servers but you cannot explore remote servers.
