“Viktor Lofgren, a Swedish software developer and consultant who created his own indie search engine called Marginalia, told me, “One part of the sameyness is that recommendation and prediction algorithms often seem to work almost too well.” Marginalia, which Lofgren started working on a year ago, is a bare-bones Web site run entirely from a computer in his living room. The search engine’s stated mission is to “show you sites you perhaps weren’t aware of.” Its results, based on its own custom algorithm and data gathering, prioritize text-based Web sites that lack ads, mobile support, encryption, and other features that qualify as good S.E.O. “Google punishes sites that aren’t up to speed with modern Web technologies,” Lofgren said. ”
