If you never had the typical childhood query “Why is the sky blue?” answered in a way that would be acceptable to anyone besides Mother Goose, you may want to re-ask the question at MatAnswers.com.
MatAnswers is an entirely user-generated forum where you can ask questions and have questions answered. Anyone can browse the site, but you need to be registered (for free) in order to ask and answer questions. The site tries to keep itself free of clutter and spammers by operating on a point system; users are ranked in the community by having carried out certain tasks (e.g., rating the best answer to a question, being the first to answer a question, etc). As the user advances up the ranks, he or she gains more credit and is allowed to ask more questions.
MatAnswers.com In Their Own Words
“Ask questions, answer other people questions and share your knowledge with others. Signup in easy steps. Use this service to solve your big or small problems and also help others to solve theirs”.
Why MatAnswers.com It Might Be A Killer
MatAnswers is a good idea, in theory. The rank system could keep users from posting irrelevant or malicious content and the points system should encourage users to choose the best answers to questions, thereby filtering responses by pertinence and legitimacy.
Some Questions About MatAnswers.com
Why would someone prefer this site over a specialized forum (say, for medical questions) or a credible search engine? By being so general, it seems like this site has the potential to grow into a hotbed of spam and irrelevant posts that the webmaster won’t be able to keep up with; why are users penalized for reporting spam? The ranking system is a little complicated and bizarre, and seems videogame-y (users can trade gold for gems???).
