Can someone please tell me the real reason they are on QnA?

Basically Mylot is a discussions site . We are supposed to discuss anything under the Sun . But I find that most of the site is filled with referral IDs to other sites , Questions and riddles and some simple queries . And whenever we know that a particular question posted here has detailed information on other web site then it is nothing wrong to provide the link of that site . I have been posting links from wikipedia so that interested persons can know more about the required subject . ( I am also a small contributor for the wikipedia ... )
