Many people often subscribe to Stack Exchange to ask the first question frequently without reading the minimum requirement to ask a question. But not only these people, also frequently users do it.
Then, it happens that this question receives four or five or more answers. Nothing else happens: There isn't a flagged answer, people do not vote for the most deserving answers, there are no comments, nothing. Simply the author of the question disappears, sometimes for years.
What function does a question described if none of the answers are correct? Is it possible to solicit feedback from the author of the question after a set time, or some reminders by email? What happened to these question/answers?
