i dont know people, what is this dorkland.
People get answers from their education, work and life experience, and from research.
Because some the people who answer the questions don't know what they are talking about :P
So that other people can know the answers.
Wikianswers does not answer your questions. It is people from around the globe on the internet that answer the questions.
Maybe it's because you are an intelligent person, they expect you to have all of the answers.
Here, we can post questions that we already know answers just to spread knowledge. Other people do it to challenge other people to know what they know.
Research:D
The people Who know about it and need answers do.
There is really no way to answer this, so it is both yes and no. Answers is a group of many volunteers giving answers. Not everyone will know it all, but given enough time, we might have all the answers. But there are some questions we cannot answer, since they are gibberish or too vague.
by being shown a new way which they aprove but didnt know existed that answers all :D
The answers come from people who come from all different walks of life and who know all sorts of things, so when they answer it seems like they have all the answers. Actually, we don't and often learn new things on here. Some people come on thinking it is funny to write nonsense, be rude or crude, and just weird, but the 700+ volunteer supervisors work at finding these type of answers/people and getting rid of them.
