I submitted the article about a week ago, because HN had just discovered Blue Lion and crashed Arca Noae's server. A commenter asked for an example of someone, anyone, still using OS/2 in production. I remembered this story and offered it as an answer of someone using it as recently as 3Y ago. So I posted it as a top-level story as well. I guess HN re-upped it and it caught on. But yes, I think that for millennial techies, this is something that came and went before they were in the industry, so for them, it is forgotten tech that they've probably never seen.
