Answer:
I am not really sure. Although I was wondering the same thing. You won't really get good answers in wikianswers unless the answer is common or like a 4th grade questions about the revolutionary war or something. That is why there is answers.yahoo.com where you get answers instantly and you could choose if you like that answer or not. You could also answer questions and get points for it. If somebody chooses your answer as best answer, you get 10 points and is recorded on your profile. Or you could just search it up it google. Hope my answer helps.
