Just found a really great link thanks to BBC News (and Google) - The Wayback Machine. It's an archive of just about every web site and it's been collecting data since 1996, and it's sooo cool! It's like looking back into history. Even clicking on the links in an archived page takes you too the achived version of that page (if it was achived too - unfortunately many links weren't), unlike the cached versions which Google makes, which just link to present pages.

Good ones to check out are Matt's site a year ago, and the first version of the first version of the Union's site - just what was "Harvey's and Harvey's"? Sounds cool whatever.
