Wikianswers are no help at all! They never have the answers!
Many people all over the world, including WikiAnswers members, tell you the answers to your questions!
Yes, most of the answers on WikiAnswers are legitimate answers. You can tell if they are legit answers by the user's trust points. ID's do not have trust points, and you are taking a chance at taking their answer as legit since they do not have trust points. Most of the answers on WikiAnswers are in fact legitimate answers.
At this time Wiki Answers Community does not tell you if someone is online.
No, wikianswers is not inferior to yahoo answers.
Because the Wikianswers crew are busy everyday, they receive loads of question in one day, which means they need a few days to answer your question.
People would have to search a wide variety of places. I like finding questions and answers in one place.
WikiAnswers is owned by the Answers corporation.
Wikianswers.
There are actually a lot of answers posted onto this site. As of August 17, 2013 there are 19,619,835 answers posted on WikiAnswers. Perhaps you wrote an answer and did not see it posted; or someone may have changed your answer. WikiAnswers is a volunteer-run site, and all of us who answer the questions do our part to keep the site growing. Please continue to participate by giving accurate answers to the questions you know something about.
That will depend on the question. WikiAnswers is one site that you can find answers for questions on. There are also many sites that specialise in particular subjects where you can ask questions and get answers.
