But not http://www.boingboing.net/2007/07/04/ursula-leguin-rips-i.html (Oh, bugger me, it's gone)
EDITED TO ADD (not there when first posted): CD's apology http://www.boingboing.net/2007/10/14/an-apology-to-ursula.html
EDITED AGAIN... for suitable values of apology of course
This has everything, Le Guin, Pournelle, Doctorow, Creative Commons, Boing-Boing, Orlowski gloating... accusations of sexism (see http://james-nicoll.livejournal.com/1019999.html )
And all about Le Guin's squib in Ansible about my old bete noir, the mainstream writer denying they're writing SF.
