I'd been occasionally reading his blog, "The Fourth Checkraise" (later, "Wingnut Musings"), for a while, and once in a while getting a link, which would bring a huge spike in traffic.
For maybe the past week, the blog's been inaccessible, redirecting to a Google login page. I can read other Blogspot blogs just fine. The Google cache is still there, for the moment, showing the last post on Feb. 6, 2012.
His book, published just a month ago, now shows on Amazon as "Out of print -- limited availability." The Kindle edition - there was a Kindle edition, right? - is entirely down the memory hole.
A search on his actual name turns up a string of good reviews on "Rate my professor", and various reports that he'd been silenced by his university for crimethink... in 2006. No news from this year.
Have the Thought Police come for him again, and bundled him into the black pink with flowers van for transportation to the Ministry of Love?
Update: no, I don't have any better information... though I note that another party's archive of the old "16 Volts" blog (which I'd never seen) has also been vanished.
I'm thinking that publishing the book under his real name may have been a mistake; perhaps, in the tradition of "A Gentleman", "J", "M", "Publius", and "Dr. A", he could have called himself "The Infamous Dr. K" or some such.
Though, with the big drive against anonymity, that option will surely soon vanish, and anyone publishing the views of, say, an opinionated moderate Republican who's good at math will find it impossible to keep his employer from learning what he says in his spare time.
