The Internet needs a good non-profit search engine that has no conflicts of interest. It could be funded by a foundation like Wikipedia or by the government like PBS, but the world sorely needs this resource.
Wouldn't that be "optimized" for as much as any other? Seems like google wants non-SEO results as much as us, if only so that advertisers are forced to spend their money directly with Google.
Not with good algorithms and curation. Sure, it will be an arms race. But another benefit is that it would be completely open, so people could build better algorithms on top of it without having to write their own crawlers, which nobody can do now with Google (at least not for free.)
