And Geocities, Vine, Google+, Anglefire, Tripod, Xoom, Homestead, Lycos communities, AOL Hometown, MSN Groups, 50megs.com, etc, etc.... not to mention small specialty sites like em411.com. All that content/history, just poof.

They found the Vine archives recently. Doesn't mean they'll get uploaded as Musk wants the new Vine to just be AI waifus. But the files still exist on a disk or tape somewhere.

I just remembered Orkut. Though I suspect Google has backups or Orkut and Google+ somewhere. I wonder if Yahoo Answers is still on a tape somewhere?
