I just read the page that you linked. I have to say, that if we hadnt read that interesting bit about how the third act is supposed to be a non sequitur, and I had viewed that strip in isolation, it would have been a pretty lame piece of work.. I suppose it was an interesting way to get the idea across, but it doesnt answer the question as to how effective a form of writing it will be and whether it will be powerful enough to hold the attention of a reader.

I also disagree that this concept is alien to western culture. Many stories use this device in the form of mini sub-plots that may go un-noticed.
