kevinmarks hm, spec says "The webmention endpoint is advertised in the HTTP Link header or a <link> or <a> element with rel="webmention" . If more than one of these is present, the HTTP Link header takes precedence, followed by the <link> element, and finally the <a> element. Clients MUST support all three options and fall back in this order."
