Hmm.

To me, the appeal of the original link was that, with one click, I could see the entire annotated-with-original-comments source of any part of the AGC. That was really exciting. A simulator (to me at least) is a lot less interesting ... and it's certainly an objectively very different kind of thing. (I for one wouldn't have even bothered clicking the current headline if I hadn't been looking for the original post's comments, which I had seen earlier.)

I'm not against curation in general -- it's a crucial aspect of HN, perhaps the crucial aspect. But I do think this particular case was a bit odd.

Ok, that's pretty persuasive, especially since most of the comments here are about the code. We changed it back.
