I think this comment is a bit strange in the present, considering search engines like duckduckgo, which is basically Bing promoted with a "we don't track" advertising campaign (also hashbangs are pretty cool). DDG is not at google numbers, I know, but you don't need google numbers to make money. I don't think privacy is a very special angle to advertise from either, promising to remove amazon-affiliate blog-spam from results for example, would be a major feature in this space as far as I'm concerned. Being able to edit searches, and potentially gain some intuition for how the search space is set up, might be a much more significant feature, depending on how people take to it. It might flop but atm I'm excited to check it out
