How can the answers provided be improved on Yahoo Answers?

I have found that the quality of answers provided by the Yahoo Community vary greatly. Approximately 60% of the people responding to questions follow the rules and make an honest effort to be helpful. Another 20% of the responders attempt to be funny, are sometimes sarcastic, and full of resentment or anger. While those answers can be annoying, their intent is usually obvious.

What concerns me the most are the remaining 20%. They provide answers in a reckless manner. Irresponsible information is disseminated in a pontifical and authoritative fashion. Their answer may be factually incorrect, but the inquirer may use that information to make serious decisions. This is a respectful question and not a rant. Do you think that in addition to the thumbs up or down icon, a 3rd choice of “Factually Incorrect” should be added?
