Actually no one is expected to read it; it's an archive of notes for me that are a bit more navigable than a single, giant page of tweets on twitter itself.
Domenico Quaranta's Link Editions is publishing the book via Lulu. I ordered a copy and can vouch for the design and quality of the printing. I think I joked at one point that McHugh's work would end up as a book but it's actually my preferred way to read this material. The blog is pure text, often lengthy, and the handsome book format cuts the eyes and brain some slack so you can focus on the ideas, which are not slack.
