@TotalSonic With a Friendica account you are automatically connected to Mastodon and Diaspora. You can also communicate with #Bluesky if you activate the connector.
I can only find a German guide about the #BlueskyConnector at the moment: Verbindung mit Bluesky herstellen

Addition: the #Friendica instance must also have the connector for Bluesky activated, not all of them do. You may need to take this into account when selecting an instance.
It is displayed when you click on the ‘i’ on the start page of the instance for information about the instance (addons, blocked instances, imprint are displayed there)
