His entries don't allow for direct comment, but he does read the replies emailed to him, and on Monday I emailed him about his comments on the possible upcoming announcement of Deep Throat's identity. I was delighted to note that yesterday Evanier quoted my email and cited me by name.
Go to the bottom of http://www.newsfromme.com/archives/2005_02_07.html. Read "Throat Culture Part II" and then "Throat Problems" to see what he said, my comment, and his reply.
And then, if you're not reading his blog, stick around for a while, as it's good stuff. It's even syndicated on LJ, at mark_evanier.
