Doesn't google have an extreme majority stakehold in search? New entrants such as duck duck go and a few others i can't think of may be at a huge disadvantage.

If yelp didn't have a review community, google could have killed their vertical search business with its semantic snippets. They recently bought zagat and are heavily pushing those results from zagat on us, so yelp may be loosing sum value there. The good thing is that these tactics cannot be done on mobile because of the way consumers interact with apps.
