It's been awesome to see archiving and Archive links become standard practice on Wikipedia. For a long time, links just rotted and were replaced. Then later, dead links would be switched to Archive content if it was available. But it's so much easier and more reliable to archive a page when it's referenced, and provide both links even while the page is still up.
It's one thing to automate dead link detection, but archiving defends against a lot more. Universities seem to redo their sitemaps and redirect all their old links about once a year. And reference pages get edited, which goes unnoticed for a long time and then leads to frustrating [Not in citation given] tags. It's incredible what a boon the Internet Archive has been to wiki sourcing.
