From the Google Knol article written about WikiAnswers:
"Over the years, WikiAnswers.com has enjoyed a colorful progression. With its roots firmly planted in the very beginnings of what is now known as social knowledge, the site evolved from the pioneering Q&A site FAQ Farm. Founded by entrepreneur Chris Whitten in 2002, FAQ Farm rapidly evolved. To capture the essence of what the site was all about and to give it the best possible future, Whitten registered the WikiAnswers.com domain in June 2004. The site and all corresponding domains were acquired by Answers Corporation in November 2006, with the product being re-named WikiAnswers."
