The very nature of archive suggests they will be filed away and forgotten by most — just as much of archive.org's content already is. I personally love it but if you want people to engage with your content, that is not the place to put it. It's like the stacks versus a window display for books — either way they're accessible, but one is for keeping and the other for exposing.

Edit: I hasten to add that a parallel upload would be a great idea, and you should suggest it to Mediakraft, the company handling the material. Their work is ongoing and an archive.org page would be a highly appropriate addition.
