Publish on your own site, syndicate elsewhere

Publish on your own site, syndicate elsewhere or "POSSE" is the idea to own the publishing part and then syndicate or "cross-post" the content to other networks. This creates independence and safety in case Twitter or the next X goes down eventually. My current setup looks like that:

graph TD A[Kraftwerk.social] -->|Publishes via Ghost.org| B((RSS)) B -->|Feeds into| C[Mastofeed.org] C -->|Syndicates to| D[Mastodon] D -->|Crossposts via Skymoth.app| E[Bluesky]

Next I am planning on adding syndication to Nostr. Still looking for a good solution for that.
