Why do Google change their posts? Up until this morning, they had a post as follows:

Cube surfeit disorder: http://googleblog.blogspot.com/2005/07/cube-surfeit-disorder.html
"Can this Googler possibly be working at peak productivity?"

This is still available in Google's cache: http://72.14.207.104/search?q=cache:googleblog.blogspot.com/2005/07/cube-surfeit-disorder.html

However, the post now reads:

Tchotchkes cubed: http://googleblog.blogspot.com/2005/07/tchotchkes-cubed.html
"Every time I pass this cube I wonder why my own work space looks so lame."

They even uploaded the image again with a different name!

Old: http://googleblog.blogspot.com/uploaded_images/ADDcube-740286.jpg

New: http://googleblog.blogspot.com/uploaded_images/Tchotchke_cube-783793.jpg

Why do they break the "permanent link" rules and change the title and content of their posts? Did the previous title offend? Did the author just change his mind? The author, Michael Krantz, is a member of the Google Blog Team – should he know better?
