This will let you view the different stages of the world of warcraft website, sometimes even including forum posts, over the years. With the earliest snapshot dating back to 2001!
I thought it pretty awesome looking through all the old Ideas and especially the forum postst from alpha/beta testers some 16 years ago :=D
Have fun!
