While I appreciate their work, they lack of completeness on their site has frustrated me for years. A huge amount of content, especially graphics from older sites, is missing entirely, and whenever anyone out there wants something taken down, it's so easy for them to lodge a complaint and get that done, thereby eliminating that important historical information from preservation. That happened to some important Japanese Mac-related sites, and no manner of talking to the folks at Archive.org would make them change their mind. They care more about take-down requests by the original content owners than historical preservation. They simply said that the original complainer in Japan would have to tell them it is okay to put the content back online before they could do anything, but those people are gone or unreachable now, so that content is lost or perhaps still on archive.org hard drives but deliberately made inaccessible to the general public. You'd think they'd have a statue of limitations on take-down requests like that, but they don't. That data will probably be in their archive 400 years from now but still inaccessible because of their policy which states the original requesters of the take-down must speak to them before they unlock the information. To me, that isn't what a true "archiver" would do.The Wayback machine can help, but if often doesn't have everything.
So much has been lost because it hasn't been truly archived. We need all graphics and all media to be archived, and the archiver should not accept take-down requests except in ultra rare cases where nuclear codes or something similar pertaining to national security is at stake.
Because of this, only those of us who are old enough to recall how it was back in the day can truly experience that again by remembering it in our minds.
