Exactly. Consider the history of the Internet. Design and content of websites have changed over the decade. Anybody archiving the Internet??
Remember back when the Web was new and the only color for website backgrounds was gray? I had several websites back then but didn't save them anywhere. Be interesting to see them again.
Remember CompuServe, Prodigy and a young AOL? It'd be interesting to view archives of those.
Actually, yes.
You might be interested in the Internet WayBack Machine, which allows you to put in a url and a date, and see the page as it looked back then.
