I like the design. I wonder if I would prefer it over Googles design in the long run. My first impression is that I prefer the clean design of Runnaroo. Not sure if I would miss all the stuff that Google throws into it, like images, places etc.
I think you are right though. Google has great organic web results, but I find the most value I get from them today are the instant answers and additional structured information that they bring in. It's to the point where I rarely need to go to any website and can find what I am looking for without navigating away from Google. Long term I wonder of the viability of Google's method of obtaining and displaying the data with antitrust considerations, but that is an ancillary thought.
My goal is to ultimately mimic this with the "deep searching" feature. Today deep searches include Twitter, Wikipedia, IMDB, Stack Overflow, and Yelp results, but I have dozens of sites on my list to add, and I'm sure I am just scratching the surface.
