I dont think any professor would consider wiki answers a reliable source. Anyone can put anything they want down. for example: did you know that president Lincoln was actually Obama's twin brother?
Chris Whitten, the founder of WikiAnswers (then FAQ Farm), still contributes on WikiAnswers.
It helps you answer questions you don't understand or need an answer to, but when people posted stupid questions and/or answers, then they are trying to make this website look bad. Like a contributor...
Yes I am on Wiki Answers, yes you are too.
The URL for WikiAnswers.com is http://wiki.answers.com or http://wikianswers.com.
Because I can't stop answering questions!!
