It is rather nice to have a cryptographer on board actually. Better yet, one with a blog to boot! Much as I am sure that Justin can attest to is the fact that for many people cryptography is a subject not understood in the slightest. On that note I shall beetle on over to Justin's blog and make a post asking him how say relate cryptography to the everyday person.
You may or may not know that Justin has actually spoken at several high end security conferences on matters of cryptography. That to me speaks volumes to not only his knowledge of the subject matter, but also his ability to convey a highly technical topic in terms that the layman can understand. Not bad for a Southerner :p
