Yes. Yahoo! Answers launched on December 13, 2005. WikiAnswers was originally started as "FAQ Farm" in 2002. In 2004 it became a wiki, and was informally known as Wiki FAQs. In 2006 FAQ Farm became part of Answers.com. In January 2007, the site officially changed its name to WikiAnswers.
Yahoo! Answers was released to the public in December 2005. A site called FAQFarm was founded in 2002. This FAQFarm eventually evolved into WikiAnswers, so WikiAnswers is technically older than Yahoo! Answers.
yahoo answers is much bigger.
As of 2009, no, Yahoo Answers still has more traffic. However, WikiAnswers has been steadily gaining.
yes
Yahoo! Answers is also a good site, other than WikiAnswers. But I recommend WikiAnswers over Yahoo! Answers. WikiAnswers is the best Q&A site and it has the best community. Yahoo! Answers isn't always correct, as well, and you cannot change the answers or spellings on there. On WikiAnswers, you can edit about everything to make the site better. Yahoo! Answers you can't, and it is a poor Q&A site.
WikiAnswers' popularity has risen over the past few years, and has surpassed Yahoo! Answers in the last quarter of 2009.

We think it is. (see the related question)
WikiAnswers is better because you don't need an account to type in an answer
(Yahoo Answers displays more than one answer and the contributor of each answer.) WikiAnswers is NOT Yahoo Answers, they are two completely different sites with different aims and reliability. Yahoo Answers is mainly a community site to air varying input on a range of topics, not provide the direct and specific answer to a question. For opinion answers, there are many sites. For factual or experience-derived answers, there are comparatively few with the scope of WikiAnswers.
Yahoo is a web portal containing links to more topics, e-mail, web search, news, web pages, answers, etc.. WikiAnswers is only designed to handle answers, but is better designed, and less ad cluttered. It is subjective. WikiAnswers is probably better than Yahoo Answers; Yahoo as a whole is more useful.
There are many websites similar to WikiAnswers. Quora is very similar to WikiAnswers. It has more features than WikiAnswers, but not as large of a user base. Aardvark is a Q&A service that is designed to get answers fast and it works well, but you can't search for questions on it that have already been answered. Yahoo answers is also like WikiAnswers, except it allows people to post separate answers to questions rather than have everyone edit one unified answer. Other sites: "Yahoo Answers" "Answer Bag" IBOBO
