XFN (XHTML Friends Network) is the network of visible links across blogs that claim various XFN relationships with/to each other. The name is a tongue-in-cheek self-deprecating parody of the "Psychic Friends Network".
Numerous examples of publishing and consuming XFN's rel=me value can be found on the rel-me page:
- Browser Support (browser extensions)
- Software Support (e.g. Mastodon, Pixelfed)
