Welcome to Mediactive 1.0 — the book version, at any rate.
Mediactive is available for purchase in print (Amazon, Lulu, Barnes & Noble, among others), and in ebook format for the Kindle and Nook. The Japanese edition, which was published by Asahi, is available there in stores and on Amazon-Japan; I wrote a new “Chapter 0” for that edition. (Here’s the Japanese version in PDF.)
