I set up brid.gy yesterday so that my Micro.blog site would get webmentions for replies to my twitter and mastodon cross-posts. So far, it’s mostly working! However, because brid.gy is built to connect indieweb sites to silos like twitter/mastodon that don’t have webmention support, they simply poll for responses and then send them to micro.blog as webmentions.
These webmentions are coming through, but it looks like Micro.blog isn’t respecting the dt-published mf2 property of the webmention that brid.gy sends. Instead, it’s just using the time of the webmention request itself (which, because brid.gy polls, can be at least 30 minutes or even hours later than the comment itself). Here’s a webmention that brid.gy recently delivered for a reply to my last post that was cross-posted to twitter:

You don’t have to read that whole log; the important bit is this:

The mf2 properties are all set up really well here; you can see that the h-entry declares its dt-published here: <time class="dt-published" datetime="2022-05-09T01:12:57+00:00">2022-05-09T01:12:57+00:00</time> but it seems Micro.blog is ignoring it.
Is this an issue that could be fixed? Based on how the comments are rendering via conversations.js, it looks like there might already some special handling for brid.gy that’s happening (e.g. in my own blog post; the replies that were sent from brid.gy show up with usernames like “twitter.com/wholemilk” and “twitter.com/adfontes__” instead of just “wholemilk” and “adfontes__”, and each reply starts with “@davidcelis” despite the @mention not actually appearing in the reply’s e-content property. Maybe micro.blog just inserts that @mention at the beginning of any reply regardless of the source?
