Samuru.com is a new search engine launched by ex SEO Brandon Wirtz last year. It's based on the Stremor technology for language and sentiment analysis and it ranks results on the basis of content, not backlinks.
Writing something the meets our qualifications for "what is a review" is much harder to game than Link spamming. You can game the system only by writing content that is useful to the user. - [news.ycombinator.com...]
Wirtz says that
Search shouldn't be a democracy. I believe the future of SEO is meritocracy. Good Content should rank, not the popular content" - [twitter.com...]
