This is awesome! It's too bad it only shows the front pages, though I assume that's because the data comes from Archive.org.
On a somewhat related note: the lack of a unified visual history for cloud apps is unfortunate! For non-cloud apps, they can just be reinstalled—if you want, you can install Windows 1.0 and ancient GUI programs. With cloud-based apps though, they're gone forever. No one will ever be able to experience GMail or "TheFacebook" circa 2005!
This is the coolest site I've seen in a long time. Kudos to the guy spending that much time in Archive.org
that's so ux.
