Khürt, a webmention wasn’t sent to my site because the URL for my post doesn’t appear on your page. The URL you’ve wrapped around my name in your post is the permalink for your post instead. The better option is to put my URL into the URL field in the Post Kinds meta box in the admin UI as seen here:
This will cause the URL to be wrapped with the appropriate microformat class “u-in-reply-to” that will trigger your webmention plugin and send your response to me. Without my URL on your page, the webmention plugin won’t send me one, and then on my end, my page won’t accept a webmention if your page doesn’t have my URL on it.
