The community there is more serious. Maybe they take better control over the answers given to make sure there is no spam and nonsense. Personally, today I discovered WikiAnswers with a Google search, and so far like it than Yahoo. The reason there are more silly and nonsense answers here is that ANYONE can answer, not just a registered user. Many IP users abuse that privilege because they are anonymous. When an entire IP is blocked, other people suffer for their foolishness.
No, wikianswers is not inferior to yahoo answers.
yahoo answers is much bigger.
yahoo
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.
As of 2009, no, Yahoo Answers still has more traffic. However, WikiAnswers has been steadily gaining.
wiki answers has more members.
I do not use Answerbag in addition to WikiAnswers. Answerbag is much like Yahoo! Answers, and has the same quality flaws as Yahoo! Answers. The answers are as-is, while WikiAnswers has an answer being worked on by hundreds of contributors until the answer is perfect.
== == It all depends on where they like to get there answers from. Because every one has a different taste on what answer sites they like the best. ************************************************************************* Well I'll start off by saying that Yahoo Answers is not any better than WikiAnswers, but to answer your question, people use Yahoo Answers either because it is the only Q&A site that they ever heard of, or they prefer having multiple opinions and more serious answers. I think people choose WikiAnswers simply because it's easier to use and because they refuse to like anthing from yahoo. I personally dislike yahoo but like yahoo answers very much.
WikiAnswers' popularity has risen over the past few years, and has surpassed Yahoo! Answers in the last quarter of 2009.
You could try answerbag or yahoo answers if you don't like wikianswers.
Jody was suprised at the level of degradation of answers on Yahoo Answers in comparison to the answers on WikiAnswers.
