Ha -- I've actually been a Digital Library subscriber for a long time due to my association with ACM Queue, and tried in vain for years to get the ACM to do something like this. I did convince them years ago to let selected practitioner DL subscribers "unlock" interesting articles, which I promptly did myself with one of my all-time favorite articles[0] -- but ACM didn't publicize the program (or really even mention it?) and to the best of my knowledge, that article was the only one made available.
Well, it seems not seeing this response in a timely manner has worked out for me as Bryan himself responded already but the joke was that he's often talked about being sidelined by doing journal study and/or obsessing over old manuals and papers. He also gave a paperswelove[0] on two papers in 2016, one of which is actually in the ACM library[1], and was involved with systemswelove[2].
Bryan, if you're reading this, I'm not a stalker. Apparently being accused of making a "submarine post" makes for a thorough reply, from me at least, even never having heard the term before.
incidentally, if anyone knows how to get hn to put my citations on separate lines without indenting do let me know, I tried a few different markdownisms but this was the best I could do.
