Why I link to Wayback Machine instead of original web content
As others mentioned, it is a good habit to request the page to be archived. You don't have to link to the archive, but you would have the option to if the page were to disappear in the future.I wish I had done this 15 years ago for a small project/website. Nowadays, my website is there, with all of its content, but most of the awesome references which I had linked to are unavailable. I wrote "most", but it is close to all of them.
