This is now online for those still remotely up with this hectic reading and commenting schedule.
part 5 link
Do feel free to jump in at this point of course. In many ways the book gets more interesting/radical as it goes on.
Also I am shortly taking down the introductory part 1 anyway, to respect my publishers wishes that I dont have too much of the book online in draft form at once (there are 7 parts in total - or 7 chunks I have divided the book into for convenience) and also because my friend James just gave me a ton of good editing notes for that section on top of the ones I already had.
If anyone wants a draft of the whole book in word format to browse & feedback on they are welcome, I just cant put it all up here at once, not that I'd personally mind that much if it was pirated and went on to have a huge impact on Chinese student populations etc. But John Wiley certainly would mind!
