I’ve wanted @mention/Webmention support on Hypothes.is for a long time. I had URL hacked my way into a solution a while back but never wrote about it.
I was reminded today that one can subscribe to an RSS/ATOM feed of annotations on their site (or any site for that matter) using the feed format and replacing the example.org URL with the desired one. Nota bene: the /* at the end makes the query a wildcard to find anything on your site. If you leave it off you’ll only get the annotations on your homepage.
If you’re using Hypothes.is in an off-label use case as a commenting system on your website, this can be invaluable. I recall Tom Critchlow and CJ Eller trying this out in the past.
To go a step further, one can also use this scheme to get a feed of @mentions of their Hypothes.is username too. If I’m not mistaken, based on some preliminary tests, this method should work for finding username both with and without the @ being included.
These are a few interesting tidbits for those who are using Hypothes.is not only for the social annotation functionality, but as a social media site or dovetailing it with their own websites and related workflows.
