You might have some grand vision of all this ties together in part 4 or whatever, but the problem is that it doesn't exist yet so we are left on discussing now this part 2, and it really doesn't stand on its own at all. Nor does the article itself state this fact that there are still two parts coming, so at least I was quite surprised when I reached the end; it truly felt like half of the article was missing. So maybe the biggest problem here was just posting this on HN prematurely, maybe it would have worked better if you'd waited until the whole thing had been published.
