'Wiki' is a type of website where members can edit anything, and Answers is the website that bought and owns WikiAnswers, so by combining the word 'Wiki' with the owner website name 'Answers' (Answers.com), it comes together as 'WikiAnswers.com', where members can edit anything freely under the Answers.com name. People can get their answers just by typing their questions in the question box, edit questions, edit answers, recategorize questions, and much more! That is the freedom of a wiki.
