I know the team has far more important things to ponder right now, but consider this idea.
When I share a new doc or an update in something like Slack or Gmail, the unfurling process engages and provides a really nice visually formatted glimpse of the content being shared.
The Coda logo could be interchanged with my company’s logo or my ugly mug.
The “Coda | A new doc for teams.” could be customised to reflect arbitrary content, tags, and links to help other invitees search better for this shared artifact.
The “Coda doc by Bill French” could be instrumented with custom text and a URL that drives users to designated content about the document and perhaps my credit earning link.
