It’s all about love, when you love someone you are more likely to swallow nonsense from the person. Same thing between Google and people, most of the thing that people will not take from, say Wikia Search, they will tolerate it from Google; why? simply love.

Technically it will burden the runtime of search and more likely have little effect on overall results.
