I did check out the example searches. First one I clicked on - Hawaiian islands. http://www.google.com/squared/search?q=Hawaiian%20islands...

What does "color" refer to here? The island's flower? What colour is melemele?

I should point out, I get what it does technically, but I'm just struggling to think of a repeatable user scenario where this would be useful...

I also noticed a couple of weird things:

1) They're not URL encoding their example searches. Tsk.

2) Searching for "google squared" on regular Google brings up Techcrunch, and the Google Squared site is halfway down the list.
