Hey IndieWeb developers! We recently added an
important feature to the Webmention spec:
discovery by <a> tag.
If you maintain webmention code or have an IndieWeb site that sends webmentions,
please add this! It should be just a few lines of code;
here’s an example.
Originally, web sites could advertise their webmention endpoint in the Link
HTTP header or in a <link rel="webmention"> HTML tag. This change adds the
option to use <a rel="webmention"> too. This is useful on hosts that don’t
allow custom HTTP headers or <link> tags,
notably WordPress.com.
This change was inspired by a big new Bridgy feature:
webmention support for Blogger, Tumblr, and WordPress.com. (More about that
soon!) Blogger and Tumblr let you add <link> tags, but WordPress.com doesn’t,
so we needed this to close the loop there.
Happy hacking!

Oh, neat! Will make sure Known is updated to handle this this week.
