A Jonathan-Knower is a person who knows Jonathan. This would, I presume, include Jonathan himself (was it Socrates who said, "Know thyself"?), if he's taking time off from photographing Half-Life 2 screens and hangin' with Dick Cheney to read this enlightening blog.
Anyway, can someone please tell him to e-mail me? I sent a couple of e-mails to his earthlink address, but they keep bouncing back. Do you suppose he has me on his spam list?
