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 tbray.org, 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.
