Ms. Dewey - Very, ummmm... Interesting

Microsoft has created this stealth search interface, which is very cool in that if they combined it with some true intelligence (inference engine) that could actually advise you about finding what you're looking for instead of presenting a list of results, they would have transformed search.

I would imagine that Microsoft sees this as one potential approach toward a more sophisticated search interface. I would imagine that Google has a lot of things like this in house.

What would make Ms. Dewey really cool is if you could select your own persona and it would evolve based on the types of searches you performed.
