How should Microsoft compete with Google in the search market? Computer publishing guru Tim O'Reilly has an answer: they shouldn't. Google's got the software giant licked, he says, and Microsoft should give up the ghost on search and focus on building software infrastructure for web operating systems. Of course, O'Reilly's spent years cheerleading for the open source movement, so it's not exactly surprising that he thinks Microsoft's future just happens to coincide with his dream. Tech Crunch writer Michael Arrington wrote a toughly-worded response, in which he argues that as cool as search is now, it's nothing compared to where we could be in ten years. (Remember, ten years ago Google had less that one hundred employees, and search was in its infancy.) But only competition breeds innovation, and the world needs someone as big as Microsoft to go up against Google and force everyone to think more creatively. Giving up the fight means retarding the enhancement of search, to say nothing of letting Google dominate all search advertising in the country.
