To the best of my knowledge, Ludovic Hirlimann‘s PGP fingerprint is 6EFBD26FC7A212B2E093 B9E868F358F6C139647C. You might also be interested in his photos on flickr, or his workplace, Mozilla Messaging. The GPG key details were checked over a Skype video call with me, Ludo and Kaare A. Larsen.
This blog post isn’t signed, the URIs it referenced don’t use SSL, and the image could be switched by evildoers at any time! But the question’s worth asking: is this kind of scruffy key info useful, if there’s enough of it? If I wrote it somehow in Thunderbird’s editor instead, would it be easier to sign? Will 99.9% of humans ever know enough of what’s going on to understand what signing a bunch of complex markup means?
For earlier discussion of this kind of thing, see Joseph Reagle’s Key-free Trust piece (“Does Google Show How the Semantic Web Could Replace Public Key Infrastructure?”). It’s more PKI-free trust than PK-free.
