Google is known for their $45\%$ share of the internet search business. Wikipedia had plans to create an open source search engine called Wikia that uses human deduction as well as a machine$-$driven algorithm. Wikipedia$$s cofounder felt that humans are better at weeding out spam search results. ChaCha employs a similar strategy and does well in Korea where Google has not been very successful. Anyone who has ever $$googled$$ a topic and come up with thousands of web pages where only a handful are useful can understand how guided search can be helpful. ChaCha$$s human$-$guided searches offer a smaller set of focused and relevant results.
