I would suggest that you put this up as a blog post, and submit the link here. It would make for a much better reading experience, especially since your post is quite link-heavy.
I've now edited the header of the HN submission to point to this URL.
Thanks for the suggestion --- I should probably have done that initially. My thinking was that I didn't want to put it on my blog, since it's meant specificially for HN. But with a little framing, that issue takes care of itself. And, as you say, the links work a lot better in a blog post.
