New, err, non-portal tools from Google

Google Co-op, beta
A community where users can contribute their knowledge and expertise to improve Google search for everyone. The user first subscribes to a provider’s content. The provider’s labels and subscribed links are then added to the user’s search results for relevant queries. Google claims that these contributions will then serve as meta information that helps Google’s algorithms connect users to the most relevant information for their specific query.

Google Trends
An extension of the Zeitgest, allowing users to track Google usage across the world. Take a peek into the brains of a few million people across the world. I’m kidding, of course.
Google Notebook
Was this needed, really? Of course, I am still getting a 404 – so I don’t know if its the fancy AJAXy stuff from Google or something else.

Oh, by the way, Google Desktop 4 was released too.
