Hypertext for all | A Working Library
Everybody who has ever linked to a third party and checked the health of links from time to time knows the issue: broken links. And we still change URLs or remove resources (yes, I did this myself a couple of times) without sending a proper redirect or notice to the user. We do that despite knowing that the hyperlink is one of the most important parts of the web. I think this is also a good place to remind you of this article, too.
