Thanks for that! I love HN discussions, they add so much to the article linked. These will too!!

This story wasn't prevented by the dupe-filter (presumably), but was your post automated?

I dunno if OP was complaining necessarily - there are a lot of cool stories to be read in the old threads too!

Not a complaint by me, parent to my comment is [the main?] mod, dang. I just was curious whether they'd implemented a side app to post links to past threads.

I'm always a bit surprised this site is not technically advanced on the front end.

Not automated. I just use HN Search the same way anyone else would (or we wish they would).

This post wasn't prevented by the dupe filter because dupeness on HN expires after a year or so. That's in the FAQ: https://news.ycombinator.com/newsfaq.html.
