I’ve installed some software on https://nhsentinel.com to syndicate posts to liberdon.com.
You should also be able to subscribe to websentinel@nhsentinel.com from any node in the “fediverse” (the federated universe of social media servers using the ActivityPub protocol). (But as of now, it’s saying the follow request is pending approval. Some chatter on the web implies this may be a caching issue and it might clear up on its own.)
