If you ask a question on Google why are we sent here,seems Google doesnt know anything?

I try a lot of websites where I could ask questions but I was not really stonish by the result. One day here in Yahoo answer I do not remember the topic but a guy named a webiste where you could ask everything you want. I gave it at try, and i can say is the best one I have ever seen. This website does not send you here for example, Google is a search engine and it gives you a result by key words.

the webiste is www.justask-it.com

Google is a search engine. Whatever you search, Google will help you the best it can for you to find that answer.

It would seem that Google prefers silence to giving a rude answer to a stupid question.

Google does not answer questions, it only shows web pages that match the words in your question.

because Google thinks that you can get bet answer here
