This blog has been cited in an academic paper!
I never got around to finishing the post up — in particular I felt it was too long — but my draft was exposed to the Internet and somebody noticed it.
Assistant Professor Joseph Reagle stumbled across my draft and wrote an in-depth paper “410 Gone”: Infocide in Open Content Communities citing a whole load of writings on the subject, including my own. I believe his paper has now been submitted to a conference proceedings (I'll update this when I find out which!)
For that reason I've gone ahead and published the draft as-is.
