I'm glad someone archived this. I had a feeling this was going to happen when I saw how new the posts were.
(It's on my to-do list to automatically mirror all HN submissions as well)
I'll add this to our hn.curiosity.ai server asap, should be pretty easy to automate as we already have post sync implemented there
I recently emailed that suggestion to dang as well - both Web Archive and Archive Today (aka archive.is/ws/ph/wh/whatever), as the former is more likely to stick around and the latter is better than 12ft at bypassing paywalls. It's on their to-do list as well.
All it takes is a robot.txt file with the right entries in it.
We need something like archive.org, but which reflects the wishes of historians and preservationists, not paranoid website owners.
