Social Cards for Matheology#

When you share a link to a matheology page on social media (Twitter/X, Facebook, LinkedIn, Slack, Discord, etc.), the platform shows a social card — a preview with a title, description, and image. These cards are the first thing most people see, so they matter.

What Is a Social Card?#

A social card is generated from metadata in each page’s HTML header. When someone pastes a link, the platform reads:

  • og:card:title — the bold headline on the card (35–45 characters)

  • description — the text below the title (140–150 characters)

  • og:card:image — the preview image (auto-generated at 1146 x 600 px)

These fields are set via .. meta:: directives at the top of each RST file. The site’s build system (sphinxext-opengraph) converts them into the standard Open Graph tags that social media platforms expect.

Example: The Matheology Landing Page#

Here is what the social card for the main matheology page looks like when shared on social media:

Social card for the Mathematical Theology landing page, showing the title "Mathematical Theology — Axioms, Common Ground" and description.

The fields that produced this card:

Title

Mathematical Theology — Axioms, Common Ground

Description

Matheology uses axiomatic logic to find where theological traditions that waged war for millennia actually agree once stated precisely.

This card is crafted to:

  1. Be self-explanatory — the title alone tells you what the page is about

  2. Hook the reader — the description makes you want to click

  3. End at natural boundaries — no mid-word truncation on any platform

  4. Be accurate — the description matches what you actually find on the page

Coverage#

Every page in the matheology section (~245 pages) has social card metadata. The current active set was generated by Claude Opus 4.6 on 2026-03-26.
