This is one case where it would be nice to see the number of votes on a comment--I upvoted you because I agree immensely, and even though I also upvoted the submission there is no way for the community to know why things are getting up voted so we have to write follow-on comments like this one.

Many thanks to OP for an excellent write-up and I, too, would like to see more of this quality content on HN!
