As the graph via TechCrunch perfectly illustrates, WolframAlpha has not revolutionized Search… at all. It is a very nice concept, but far from delivering any real everyday value other than being somewhat useful to find numeric facts.
By comparison Bing has resulted in a good surprise to put pressure on Google monopoly in Search. No Search Revolution, but at least some good competition. That is excellent news for all of us.
An today’s news of Bing Travel launch look very promising.
