The first speaker at TAM4 was Christopher Hitchens; here's his bio from the TAM4 site:
Christopher Hitchens' trademark savage wit flattens hypocrisy inside the DC Beltway and around the world, laying bare the "permanent government" of entrenched powers and interests. He's the author of many bestsellers. From Mother Theresa to Michael Moore, no one is above scrutiny.
A quick summary of his talk (also from the TAM4 site):
"MR. JEFFERSON, SHORE UP THIS WALL!"
TAM4 begins with a BIG BANG as controversial journalist Christopher Hithchens celebrates Thomas Jefferson's Enlightenment views, whilst pillorying those who fabricate "design" and want to tear down the wall of separation."
The author lives in Vancouver, Washington, USA with his girlfriend and a menagerie of cats, rats, fish, birds, guinea pigs and robots.
Among other inanities, he strives to use investigative techniques to work young starlet breasts into every aspect of rational discourse -- focusing on the discourse, thus making it not perverted. Also, has recently begun a career as "Internet hairstylist."
He can be contacted via email and Jabber IM at 'email@example.com'. He likes to be contacted.
(All press inquiries, however, ought be directed towards the author's agent, Alistair Hoel, via email to firstname.lastname@example.org.)
