In June I added link preview cards (or unfurls) for bookmark embeds from Ghost and Substack. That was two platforms. This month the list grew a lot longer.

Forums expand links into boxes, WordPress themes ship "blogcards", newsletter platforms embed article cards. They all carry mostly the same fields, a title, a short description, the source, a thumbnail, but every platform invents its own markup for it. Without special handling, that markup reaches the reader as a broken pile of divs.

Feedstand now recognizes each of these shapes and folds them into one link preview format, so they all render as the same clean card. The cards also keep the caption the author wrote under the link, and show a small label of what kind of link it is.

The support includes:

• Blogging platforms: dev.to, Medium, Tumblr, Hatena, Ameba, Tistory
• WordPress themes and plugins: Cocoon, SWELL, AFFINGER, TCD
• Forums: Discourse, XenForo, NodeBB
• Embed services: Embedly, Paragraph
• Open standards: microformats citations

Link previews are one small piece of a bigger plan to bring rich content into the feed reader. There will be more to say about that soon.
