There is a huge amount of questions on the site. So it isn't always possible to know that the question has already been answered. Questions asked with the exact same wording, will be merged into existing questions. If a new form of wording comes in, less experienced users may just answer it. Experienced users and supervisors will look to merge it. You could also ask why do people ask questions that have already been answered? In the same way, they don't know it has been asked already and if they use a new wording, they won't find the question, so they will think it is the first time it has been asked.
Yes, some people answer their own questions on the site. As long as a question is answered properly, any answer is valid no matter whether it was your question or not.
We the readers answer the unanwered.
Because only one person has answered that particular question. The more answers that appear are more people answering you.
so people can answer.
Because it is answered by people and not the internet. Plus people don't know every answer
You type a question into the large text box where it says 'enter question or phrase'. Then WikiAnswers will check to see if the question has already been asked, if so you can read the answer. If not the question will be posted to the Internet and anybody can answer it. The answer time for questions can vary depending on the number of neeks (clever people with nothing better to do like me) online answering questions. It could be seconds or days. Unfortunately because loads of people ask stupid questions that waste people's time or ask questions that have already been answered the whole process is slowed down.
You can asking things people don't know at all
It all depends on the subject matter - and whether the question is placed in the correct category. There are literally thousands of knowledgeable people using WikiAnswers - you simply been to make sure that...(a) your question is a valid one (a question such as 'how tall is he' could never be answered !)(b) your question is placed in the correct category (some people only browse a few categories of personal interest)In addition, many people prevent their question from being answered- they repeat the question in this part of the form. Seeing that, the computer considers that the question has been answered, and sends it over to the "already answered" pile.
Me. Me. Me. Me, oh sorry, have I already answered this?
a bowl of food is when you have this round; ceramic jar that is filled with food we people eat. i hope that answered your question... (which i think you already knew)
Not all answers are inadequate. These questions are answered by the public, so some people could just say stupid answers but some are quite adequate
This question cannot be answered. For this question to be answered you will have to give me more information and details like what the ages of the people are and how many people there is.
