Personally, I like giving answers. All of our supervisors like giving answers, and our dedicated contributors do, too. They wouldn't be on WikiAnswers all the time if the didn't like giving answers.
Because there are just random people giving random, but maybe accurate answers out there. Like me.
You know when you are giving inaccurate answers when you don't know the answer. If you believe you sort of know the answer, but don't really know it, chances are that you are giving inaccurate answers. It is up to you whether or not you know when you are giving inaccurate answers.
A human being just hasn't come across that queston yet. We have like 25 million questions.
You will not get blocked for giving the wrong answer. However, if you are purposefully giving out wrong answers, you will be warned first before being blocked. This goes for most situations, like posting inappropriate answers, posting spam, or posting "search Google." Should you continue to do this even after being warned, you will eventually be blocked.
Not a single person - there are many thousands of people contributing to the site.
Why would we answer like that?.... we answer to improve your knowledge. :) If we give low-quality answers, they would only be deleted or changed, so there is no need for us to waste our time giving bad answers.
What was the question
anybody
opinions
Random people who know the answer and that are signed into Wiki Answers.
This site gets their answers from the general public, meaning, random people. Amongst these people are some who are not as smart as you may like therefore giving answers you may see as dumb.
Look at me now! I'm answering your question! Of COURSE I can give answers! So can you... Yes you can just click on answer if you feel you would like to answer a question or on improve answer if you feel you have a better answer.
