I would change any links you have pointing to Imgur. But as for storing the contents, wasn’t it just a site for memes? I can’t recall a single time over many years seeing anything worth preserving that wasn’t essentially throwaway content.
Well, one (semi-)frequent use case for me would be creating some graphic (e.g. a chart or a UI suggestion) that I would share in some community (e.g. forum). Unlikely anyone looks at them again a decade later, but those embeds will still rot away...
That is an incredibly narrow view of what imgur is used for. Over on the Something Awful forums there is a _ton_ of amazing content with all of the images hosted on Imgur. Stuff like woodworking and other craft blogs, video game playthroughs, collection photographs, musical instruments... I'm sure many other online communities use it for the same purpose. When imgur dies (this announcement is a very loud death knell) it's going to be a huge, huge loss.
