Yahoo answers questions
According to Yahoo Answers,you need to be 13 to become a member of Yahoo Answers.
No,you can't.Yahoo Answers is launched by yahoo,so hence,to create a yahoo answers account,you need to have a yahoo account.
No, wikianswers is not inferior to yahoo answers.
You can ask or answer questions at yahoo answers at any age,but Yahoo Answers says that you need to be 13 to create a yahoo answers account,same for Facebook,Wiki Answers and many other sites.
== == 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.
Yahoo! Answers URL http://answers.yahoo.com/ It is pretty much the same but I think WikiAnswers is better.
You could try answerbag or yahoo answers if you don't like wikianswers.
