i don't know about revolutionize, but i think it fills a particular niche that was lacking.

some people want an article... and links to more information, adding relevant news results and videos gives a well rounded page that has a lot of information on any given subject.

by adding the article they have improved on what google and other search engines are doing... as they will sometimes now bring up news and video.

then adding twitter, mahalo answers, products and more they've improved even more.

i haven't seen any search engines out there that have all of this.... add to that the human aspect and the ability for people to make money by contributing and it is definitely revolutionary, even if it does not revolutionize search engines as a whole.

just my 2 cents...
