There&#x27;s a useful summary on the wikipedia page for &#x27;Linkback&#x27; [1] describing how Webmention differs from other similar schemes.<p>Things like Pingback and Trackback seemed to be all the rage for a few months, back in the day. They then seemed to cease being talked about - either discussion has bypassed me, or they just carry on being used, seamlessly, or they&#x27;ve failed. It would be great to see something like this really take off, though, especially since many bloggers started turning off comments.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Linkback" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Linkback</a>
