Oh I think it's well known and has gotten a lot of attention. In fact HN probably did a lot to expand awareness that it existed, since a lot of people here originally found out about it from PG's site. It's a bit of a puzzle why there weren't more comments on those old threads, but that's a different question.
You've got to be a good reader to begin with plus have an interest in research which there is plenty of interest.
Maybe once you get through the whole thing you have to be able to pick your jaw up off the keyboard to make a comment or there is no record of it happening?
