apparently Microsoft realized the buzz had got out of hand...
"In an interview yesterday, Mika Krammer, a Microsoft marketing director involved in the project, explained that Origami was merely meant to be the code name. She said the volume and breadth of buzz created by the cryptic Origami campaign caught the company by surprise."
But credit Scoble at Microsoft for creating the buzz and feeding it in blog world (though on his blog he deflects the credit/blame). There is a new channel out there (courtesy of Google!) and Microsoft is learning how to use it.
