POSSE: Why We Publish on Our Own Server First

POSSE: Publish on your Own Server, Syndicate Everywhere

Cory Doctorow doesn’t just write about platform independence — he lives it. Every post starts on pluralistic.net, then flows to social media, newsletters, and aggregators. The canonical version lives on his server. Everything else is a copy.

We follow the same principle at SanMarcSoft.

Why POSSE Matters

1. You own your content. Platforms change algorithms, shut down, or enshittify (Doctorow’s term). Your server doesn’t.
2. You control the narrative. No character limits, no algorithmic de-ranking, no “community guidelines” reinterpretation.
3. You build a trust chain. With C2PA signing, content published from your server carries cryptographic provenance. Syndicated copies can be verified back to the origin.

Our Infrastructure

• Hugo generates the canonical content
• GitHub Actions syndicates to Brevo (newsletters), target blogs (cross-repo publish), and Buffer (social)
• Curator aggregates relevant industry content alongside our own
• Every piece is signed with C2PA Content Credentials at the origin

The Syndication Flow

Your Server (Hugo)
    ├── Newsletter (Brevo)
    ├── Blog (cross-repo publish)
    ├── Social (Buffer → LinkedIn, Twitter)
    └── Aggregator (Curator)

The content lives here first. Everything else is amplification.

Building tools that earn trust in a world of synthetic content.
