Hacker News Reader

This is a very interesting programming language concept that I didn't know of before. Highlighting the kind of work that risks getting lost as time goes by is where HN is at it's most valuable. I'd take this over 99% of the other stuff that reaches the front page, 404s be damned. It's a feature and not a bug that not everything is about the thought leaders of the day and the news cycle hysteria.

Because it's an interesting concept for a computer language, and the HN community can reliably be counted on to find other sources to dive into. HN has been known to deep dive on software archeology.

Sometimes people just like a curiosity. From a glance this seems like a curiosity (it's also dated 2013, so that might explain the 404s)
