"DuckDuckGo is a three-year-old search project with venture backing that promises to torpedo the business model Google and Microsoft's Bing are predicated on: making money from your search data by selling it to others."
Well, I'm all for torpedoing any monopoly of information. However your business model is a little off... SBBs (Search Big Brothers) make money when people use their search engine by way of the pay-per-click business model (simplified take on today's model, but true enough). They do get a little fluff when they sell the user data, but its nohere near another PPC battleship of a business model.
I'm really quite excited by the peer-to-peer search projects underway.... this is the most likely way to achieve large scale success in making censors and marketeers impotent once again.
