Thank you! It did cross my mind. I've archived a couple of the hard-won links in there that I had a feeling at great risk of rotting. But thankfully a lot of the links are to GitHub pages, so I'm not so worried about those.

Unfortunately, I think the article's readability would suffer if every single link were followed by an [archive] tag. Wikipedia have a better setup for providing both an archive link and a live link, which unfortunately the newsletter format doesn't really lend itself to.

I think copying the links as-is into the Wayback Machine will generally do in a pinch – just a bit of a pain to find the right month to roll back to.
