<p>After looking into it more, the only addition needed now is <code>og:title</code>, set to the same as <code>title</code>; some sites, like Slack, only pay attention to the OG tags. </p>

<p>Facebook uses <code>title</code> if <code>og:title</code> is not set, so ok there. Could consider adding support for <code>X-Facebook-Locale</code> as <a href="https://github.com/pnorman" class="user-mention">@pnorman</a> suggests, later on.</p>

<p>So in summary, I think adding <code>og:title</code> set to <code>printable_name</code> should be sufficient to close out this issue.</p>
