Similar to the design set up for other comment types, it would be nice to have a filter for refbacks in the dropdown menu at /wp-admin/edit-comments.php. With the Webmentions plugin enabled, one is presented with the options to filter for “All Comment Types”, “Comments”, “Pings”, and “Webmentions”. Adding a filter for “Refbacks” would be incredibly helpful as well.
It took me a moment to realize what it was exactly since I hadn’t yet added a field to indicate it, but since the IndieWeb chat doesn’t send webmentions by itself, I’m glad I support refbacks to be aware of comments on my posts. The avatar didn’t come through quite like it should, but it’s nice to be able to treat refbacks like any other type of mention.
The chat has some reasonable microformats markup, so I suppose the parser could do a more solid job, but this is a pretty great start. Sadly, Refback isn’t as real-time as Webmention, but it’s better than nothing.
I suppose we could all be posting chats on our own sites and syndicating into places like IRC to own our two directional conversations, but until I get around to the other half… (or at least for WordPress, I recall having gotten syndication to IRC for WithKnown working a while back via plugin.)
Refback is a linkback method that works using the standard HTTP Referer header. Like pingbacks, trackbacks, and webmentions, it attempts to present links of other sites that have linked to you. Unlike other methods, the other site requires no additional support. The implementation works exactly as the other linkbacks do in WordPress.
