Thanks for checking out the plugin, Justin!

The example in your screenshot is a perfect way to highlight what is possible with webmentions. If the Tavern had webmention support enabled (one day!), the full text of that note would appear as a reply in the comments of the Blogroll Block post used in the reply to field.

One of the main itches I'm trying to scratch with this plugin—besides just owning my content—is the ability to leave comments on peoples' sites from my own place on the web.
