I find the whole thing funny. There's not so much secret sauce going on here as much as you might think. I've been reading Daring Fireball for a long time but I think anytime you make this suggestion the automatic response is to think there is some shady cabal behind the scenes and that's just conspiracy theory stuff. Anytime someone makes a meta post questioning how HN ranks articles it almost always gets flagged because it's not really on topic.
I don't have nearly as sophisticated setup as [Gwern](https://gwern.net/archiving), but they provide an overview of how you might go about it. Right now I manually use the extension on as as needed basis, but I would like to get it to the point where I can point a script at a list of urls and both run SingleFile and also upload to the Wayback Machine
It really depends on your needs. I use Pinboard on many different browsers and devices and I'm not really interested in running my own service. I'll happily pay for the full text archiving but I acknowledge it is not perfect. I have come to the conclusion if you want to retain full text copies of your bookmarks, you need to download the pages yourself. I have been using SingleFile extension but there is also a CLI available.
