The system matches words in the question being asked - to see if they are already in use in another question. It also looks at the subject matter - to check whether similar questions already exist.
There is a text search engine in the system which indexes and compares the text you have entered against similar test already know to the system. These are then presented to the user who can then make the decision about weather the question (using different wording) has already been asked. If so then the user can get an immediate answer.
Also the systems volunteer supervisors may merge newly asked questions with existing answers when it is obvious that the new question is the same as a question already in the system.
Questions are also categorised to help users look for answers under broad top groupings.
The software is designed to "look" for key words and phrases and match those up.
The question you asked is inappropriate for WikiAnswers.

WikiAnswers does not have to pay money for each question. Questions are asked by the site's users, and are free of charge.
New questions are coming in constantly so there is no way to tell you the most recently asked question.
If you are a registered user, you can go to your contributions page by clicking on "My contributions" on the blue sidebar. Then chose "filter by: Questions Asked" and you will see a list of all the questions that you have asked on WikiAnswers.
Limitations in the WikiAnswers database do not allow certain characters to be used in questions. Also, we would be reluctant to add commas to questions, as parentheses would allow many different variations of a question to be asked. See Related Question.
WikiAnswers doesn't 'block' inappropriate questions, but rather stores them so no one can answer an inappropriate question that has already been asked. It is called a 'Catch-All', and it stores all of the inappropriate questions so when a user types in an inappropriate question that has already been asked and merged into that Catch-All, they will get an answer telling them that inappropriate questions are not allowed on WikiAnswers. In a way, WikiAnswers does 'block' inappropriate questions.
"Enter a question here" is the box for you to ask your new question on WikiAnswers, or to ask questions that may have already been asked and answered.
