My original plan was to have the first run available for purchase at Further Confusion in January, 2012, but due to my poor planning that ended up not being possible. However, I will definitely be selling copies online, and most likely at APE 2012 in San Francisco.
Of course, backers will get their copies before anyone else!
It turns out that shipping the book to Canada costs only slightly more than to the US, so feel free to just do the normal pledge if you're in Canada (although I wouldn't mind you throwing in a couple more bucks to cover the difference anyway).
The book organizes the whole story together into a single bound full-color volume with clear chapter markers (including all-new chapter title pages) and a table of contents for easy perusal. The comics are also included at their full working resolution, rather than the 33-40% reduction they're presented at on the web. I also plan on having content in the book that isn't on the website. Finally, it's a nice way to show support for something that you may have enjoyed.
Not only is there a comprehensive endnote section that includes all of the popup text with easy cross-referencing between the comics and the notes, the endnotes have their own footnotes that explain the more oblique references! So in case you have no idea what I was referencing with my highly-referential and generally-weak attempts at snark, now you'll finally find out.
