Why is Yahoo answers better than WikiAnswers?

Answer 1

* WikiAnswers' answers are condensed into the best available information, not a major discussion panel for each question. * Many of the contributors here are experts in, or have a large amount of experience with, the various categories they often answer in. * The questions and answers here are split into categories, subcategories, and even sub-subcategories, in order to make finding a particular subject easier. * Each category (etc.) also has its own Supervisor, someone who has demonstrated that they are extremely competent in that area of knowledge. The Supervisors keep track of vandalism, who is making good contributions and help those who need it most. * When a new question is asked, an automated system checks the whole database for similar questions or those containing the same keywords - this makes finding an answer, even when the wording is not identical, easier.

Answer 2

Question StructureWikiAnswers is designed more to answer universal and relatively simple one line questions.

Yahoo answers can answer more complicated and personalized questions.

AudienceYahoo currently has a wider community who comes to both ask and answer questions. As Yahoo is a web portal, people who come to Yahoo for other things (eg. web search, e-mail or news) may also find themselves asking or answering questions. The personal nature of Yahoo attracts more people to Yahoo.

WikiAnswers has a smaller user base, and is not tied to a major portal.
