Here it is : http://desktop.google.com/
DaveWiner's "morning coffee notes" on Google's desktop search : I've already learned, long ago, if I want to be able to search something I just need to publish it, and eventually it'll show up in Google. I just have to be willing to share it with the world. In a way this is a Lessig-like scheme to get me to CC my content so it can be part of his cool new website. But of course the website we all want to be part of is... Google (not the one on my desktop by the way). So basically search is just where it needs to be, after all. We didn't really need it on our desktop where it potentially exposes all our passwords and secret desires, which of course we don't want exposed.
