I wasn't using HN back in 2015 (let alone in 2009) so I'm glad this was re-submitted. It's been more than 4 years which is sufficient time for new users or for people to come back to it with new opinions.
It's interesting to see what people thought 4 or 10 years ago about the same article. Those links aren't to chide the submitter that it has been submitted before, HN explicitly allows reposts after a year or so.
Ah, thanks for explaining that. I'm more used to Reddit where re-posting links is more common but also more frowned upon, so I'm still unfamiliar with the culture here.
Sure. Reposts are fine after a year or so. This is in the FAQ: https://news.ycombinator.com/newsfaq.html. The purpose of linking to previous discussions is that many readers are curious to read them.
