Which is funny. Google beat other search engines in the early 2000 because it actually did find what people where looking for, not what the "search engine" wanted people to see.
Now it's more and more the latter, I imagine because it's more lucrative for Google to display the results advertisers pay for...
That's really the product of the lack of competition in the search space. Nothing more. Why should Google bother? It would take billions in VC for a competitor to truly threaten Google dominance on search.
Same with Youtube. Youtube straight out doesn't care anymore about search terms and will just show some results Youtube "cooked up" for the user, unbelievable...
