The problem is that commercial search engines are inherently conflicted: they have products to sell and advertisers to please. The question is: Should search be a public service, like a library?
The French are taking on Google books with Polinum, the "Operating Platform for Digital Books." Jimmy Wales's efforts with Wikia Search failed because they didn't execute and weren't profitable. Daniel, a long advocate of transparency in search now works for Google.
