I'm afraid i don't understand the argument here. What is the use case here?<br>
<br>
0) something is published on twitter account "foo" and i want to know<br>
to whom to attribute authorship.<br>
<br>
1) i regularly communicate with "foo" on twitter, and i want to know<br>
how to communicate with the author in other communications channels.<br></blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">2) You want to communicate with me, Tim Bray, and go looking for a key for me. You discover that there is a directory of keys, and you can retrieve a public key from it, and the corresponding private key has been used to sign a time-stamped tweet from @timbray and gist from github/timbray and an assertion at <a href="http://tbray.org">tbray.org</a>, and because you know who I am on Twitter and github and what my personal domain is, and you can check the signatures, you are prepared to believe that that public key is appropriate for communication with me.</div><br></div><div> </div></div>
